The developers plan to use KDE 4.13 for kubuntu 14.04 - makes some sense as its 5 yr support.
The KDE 4.13 release schedule is roughly the same time as 14.04 release - this means there may be more bugs initially but better 'long term'.
That is unless done major breakage occurs

Whatever costs would be needed for a full scale migration of the NHS to Linux the savings over decades would outweigh those costs. Not to mention reliability and security - even the UK gov has said Ubuntu is more secure than Windows8/Mac
http://news.softpedia.com/news/Ubuntu-12-04-Is-More-Secure-Than-Windows-8-and-Mac-OS-X-Says-UK-Goverment-416016.shtml
It would mean the tax payer no longer forced to fund an anti competitive patent troll also, another bonus would be the tax payer would be funding technological improvements for the entire world, not Microsoft's patent lawyers.
I went to an NHS hospital the other day and on a large computer screen (used in reception) it had a post it note that read ' When you lose networking reboot computer' ..... It was running Windows - I can't imagine a Linux desktop ever having that note on - I wonder how much productivity is lost just in that one reception thanks to the NHS using windows - can only imagine how much productivity is lost for the whole organisation.
Also regarding IOPS -
ftp://public.dhe.ibm.com/linux/pdfs/KVM_Virtualized_IO_Performance_Paper_v2.pdf
" It also details test results that demonstrate that a single KVM
guest can handle more than 1.2 million I/O operations per second (IOPS) at 8KB I/O request
size and more than 1.5 million IOPS at 4KB and smaller request sizes – the
highest storage I/O performance ever reported in a virtualized environment."
So your statement regarding VMWARE /HyperV IOPS speed being greater than KVM was just plain wrong....
I can only assume your benchmarking was also.
Did you house your Windows VM in an LVM partition, instead of a QCOW image?
Only when I do that coupled with the cache settings NONE/NATIVE does Windows IO speed outperform other types of virtualisation - i.e you NEED to install inside an LVM partition (and use Virtio drivers to get 'proper' speed)
Also your wrong about IOPS. KVM currently holds the IOP's world record...
http://forsetti.wordpress.com/2012/06/28/kvm-technology-review-and-roadmap-update/
'KVM has achieved World Record IOPS: 1,402,720 IOPS on a IBM x3850 X5 for 8KB request using 7 SCSI pass-through devices.. For 1 KB requests, can achieve 1.65M IOPS.'
As long as you set up the KVM vm correctly - i.e install in an LVM partition, set correct cache settings and use Virtio drivers it will outperform all other types of virtualisation.
You HAVE you use the Virtio Disk drivers (as your installing in an LVM partition) or the Windows installer will not see any drives btw.
(correct cache settings = native,none)
Try it, benchmark it and you will see
OpenSuse's implementation of KDE has always seemed that bit more polished. Compared to Kubuntu 13.10 KDE seems a but snappier and the base system more stable... i.e the original release of Kubuntu 13.10 broke on UEFI installs - without an internet connection (to get updates) even now you cannot install Kubuntu 13.10 in UEFI mode (unless you chroot into the system and fix it..)
KDE I have thought for a long time is the nicest desktop for any OS - MS 'borrowed' a lot of early KDE 4.x features for Vista/Windows7. Windows 8 seems to be a Unity/Gnome3 clone (worst of both worlds)
KDE4.11 has so many nice little usability features the most you use it the more you will never think of bothering to try and work with Unity/Gnome3
p.s you can install the Nvidia drivers now 'the hard way' - i.e via the binary from Nvidia.com (like those windows barbarians have always had to - rather than use your package manager - like the master race are used to). One good thing about using the binary is that you will always have the latest version (unlike the opensuse/debian/ubuntu repo versions)
http://en.opensuse.org/SDB:NVIDIA_the_hard_way
If your company/organization is pathetic enough to still be using this shit then you deserve whats coming to you, and ultimately unless you have migrated to Linux / Mac that will be Windows 8 - enjoy working with that won't you.
Seriously there is no excuse.
Personally I can't wait until the police/hospitals,etc waste our tax on shiny new PC's to run Windows 8 (instead of saving money in the long run with Linux..)
The same can be said for Kubuntu also.
If your a gamer you are better off with KDE over Cinnamon... (enable suspend desktop effects for full screen apps and disable VBLank in nvidia-settings and you'll most likely be running games faster than Windows 7/8 - Nvidia users only.)
Games are faster on non Gnome 3 desktops (with Nividia) and some games are not playable fullscreen on any gnome3 based system that is a lower version than 3.8 (i.e Unity,Cinnamon,elementary, etc)
KDE gives you the best of both worlds in terms of being able to actually do any work and being able to play games fast.
Mints desktop (cinnamon) is nice however just seems a bit rough to me (and have the issue of being based on gnome3)
But Microsoft said that our privacy was important... Whilst giving NSA access to their servers.
Hold on, if Microsoft lied about that why does anyone trust that their products like Windows do not have deliberate backdoors in also ?
Stallman wasn't paranoid, he was right.
Linux is the only major OS I can trust.
Flexibility in the sense that an image can be converted to other hypervisors 'easily', the ability to resize partitions inside an vm image regardless in they are the first partition on the disk (i.e /dev/sda) - see virt-resize. Flexibilty due to the fact you can script in a Linux environment which is years ahead of 'power'shell.
There is a reason most of the big hardware players are fully supporting and getting behind KVM - i.e IBM, HP, Intel i.e
http://openvirtualizationalliance.org/blog/why-does-hp-believe-in-open-source
"KVM is a great fit for HP customers. Using HP cloud-optimized servers; web hosting service providers can roll their own infrastructure, enterprise customers can deploy integrated hardware and software solutions, and everyone can deploy application workloads in the HP Cloud."
> Hyper-v Server has outperformed KVM ever since the release of Hyper-V Server 2008 R2
Utter rubbish = seriously do benchmarks, KVM out performs Hyper V in IO by a serious margin when setup correctlyu - i.e LVM + virtio + correct cache settings.
> Fro instance show me a KVM host running a single VM with 1 million IOPS like Microsoft demonstrated last year?
KVM has achieved World Record IOPS: 1,402,720 IOPS
http://linux.uits.uconn.edu/mas02041/2012/06/28/kvm-technology-review-and-roadmap-update/
> Also worth noting that KVM is limited by having to run on top of a Linux OS, whereas Hyper-V Server is a dedicated Hypervisor OS (like VMware ESXi)...
You do know that ESXI is still forked from the Linux kernel also - see ovirt (ovirt.org) - its a Linux ESXI equivalent.
It should like at least half your beliefs are just assumptions not fact.
Well done Microsoft for realising that certain things are far far far more efficient doing them on the CLI..
Shame your 'hyper-v' will still be years behind Libvirt/KVM in terms of flexibility, performance (if you use LVM+virtio for disk) and cost (£0)
Anyone who thinks KVM's performance is behind Hyper-V hasn't done it right - Windows VM's are very fast if you choose virtio and use the NONE cache setting in advanced IO.
If you want actual choice your running the wrong OS.
Linux you do have choice , kde cinnamon, elementaryos are all great usable desktops (most are except unity/gnome3) - also the kernel is appartantly 1/2 a decade ahead of the Windows one...
http://www.zdnet.com/anonymous-msft-developer-admits-linux-is-faster-than-windows-7000015236/
It will be in Ubuntu (or if you have sense Kubuntu) by 13.10 - however anyone can run it right now.
Of course you can compile it yourself (I also do compile my own to get the old oss sound modules...) or if your not skilled in this are you can use the mainline ppa
http://kernel.ubuntu.com/~kernel-ppa/mainline/
- i.e you can get it now.
I imagine Arch will have the kernel days after the final release also.
I absolutely hate Unity, however the Ubuntu base is great and swapping desktops is easy (Kubuntu I find better than Windows 7 to work with)
And that is the great thing about Linux in general, you actually have choice.
Windows 8 users, what choice do they have?
If you running a Nvidia card and not running any Gnome3 based desktop (like Unity) FPS in games is higher in pretty much all games I have tried in Linux - just use a non crap desktop.

I take it your happy for dissidents in Iran/China, etc to be rounded up (due to not having Tor)?
This country is only a few steps away from anyone who wants *any* privacy online from needing systems like Tor.
All I can say is 'try it' - its pointless - it will be be a waste of money to even try.
http://arstechnica.com/tech-policy/2012/04/tor-traffic-disguised-as-skype-video-call-to-fool-repressive-governments/
"Computer scientists have released a tool that disguises communications sent through the Tor anonymity service as Skype video calls, a cloak that's intended to prevent repressive governments from blocking the anonymous traffic."
Tor is still used in Iran/China (even though there has been a recent attack against obfuscated bridges - https://lists.torproject.org/pipermail/tor-relays/2013-April/002089.html

I have a problem with being forced to fund a company that damages innovation for all and doesn't pay its fair share in Tax.
What I mean is the fact that schools, hospitals, police, etc are all using Windows desktops still when there is absolutely no need (better) free alternatives exist. his is due to the fact they got a monopoly during the 90's when competition didn't really exist and use tactics outlined in the Halloween documents (at the end of the 90's) to keep their position by ensuring that competition cannot viably exist and 'customers' get locked in forever.
I'm going to have a major issue when schools/public services want to spend my hard earned money on their Windows 8 'upgrade' , unless they stop using Windows that is where they are heading.
This could be a great thing if they abide by the GPL....
Unlike out silly country where the tax payer is forced to fund a known monopolist patent troll through tax, the Chinese tax payer could fund innonvation and technology improvements the entire world can use.

> Changes to Windows and MacOS over the years have been incremental and careful.
Sounds a lot like KDE (since v 4.0 at least) - you know the desktop that a lot of Windows Vista/Window 7 features were 'lifted' from (i.e the menu for a start)
Every few months a new, slightly better more refined version comes out.
After using KDE for a while most users would feel limited using Windows 7 (I am not even going to mention the Unity clone - Windows8)
