Re: Replace outlook!
Thunderbird is shit - I've had to switch to Evolution.
Sorry, but T-Bird seems to struggle with odd little things - the Lightning extension for calendars in particular.
There is - and always has been - a Linux-shaped hole in the desktop OS space, just ready for the first company to actually seriously build a looks-like-Windows, acts-like-Windows distro. But for some reason (which suggests the free market is shit) they simply haven't.
Part of the problem is the Linux' desktop strengths - diversity of apps, customisable beyond belief to name two - are actually what scares the horses. Imagine trying to deliver a Linux desktop in a non-trivial (>20) user space.
If someone could come up with a straightforward Linux desktop, with a settled GUI, and a Windows approach to installation and operation, and a bombproof email/calendar program (not "app") that could connect to Exchange if needed, and that could run click-for-click versions of Word/Excel/Powerpoint, then you'd probably be able to put it on 80% of the corporate desktops and few would notice.
The fact that no one seems to have worked that out yet - and been willing to back it with cash - suggests it's not something that interests the Linux community.
The closest we've probably got is Mint. Which still needs some techie smarts to get around. Even then we hit snags like the Evolution calendar widget (which provides an Outlook feature) won't work on Cinnamon. (Guess what the default Window Manager is ?). True, you can switch to GNOME to have a working widget. At which point you've proved the Windows fanbois point.
All of that said, it's curious that when it comes to computers, an awful lot of megacorps really have backed a single horse, which means they are incredibly vulnerable to any flaws in that landscape. Surely for the sake of resilience, there should be a driver to run different desktops ?
