I've just bought a brand new laptop (Medion online) which came with Windows 8 installed. I tried it for about a week before I gave up even trying and had a dilemma between going back to trusted Windows 7 or for a brand new Linux Mint 17 installation with Cinnamon. I've went with Linux and so far it is turning out well.
It hasn't been all straight forward, I had issues with my wifi drivers as the wifi would randomly drop after about 5 minutes. An upgrade of the Kernel to the latest version managed to resolve this. Apparently my wireless chip is quite new and wasn't well supported in previous kernels.
There have been other strange things, like the difference between exFAT and FAT32 on USB sticksa and how you need extra packages installed to read these on Linux. It didn't take long to sort.
I did have a bit of issue with the video drivers that were installed by default as I was getting serious tearing with youtube videos. I added a ppa repository and updated to the latest nvidia package via that and everything has been stable since.
Chromium is the best browser I've used as there were issues with running a video full screen with firefox as any activity on the second monitor would cause the fullscreen to quit. No such problems with Chromium.
I couldn't get Linux Mint to boot at all with UEFI on this laptop no matter what I tried. I ended up giving up and going back to BIOS as there is really no difference apart from maybe a couple of seconds in speed on bootup. The hibernate/sleep function is unstable. My laptop will almost definitely give a hard freeze (ie alt+f2 won't even work) and I have to do a reset by holding down the power button for 6 seconds. This is unfortunate but I've decided I can live with it for now. I may find a solution in the future. For some reason my brightness up/down settings occasionally stop responding and I have to restart the laptop before I can change them again. Oh yes and if any of you use the CAPS lock key rather than shift for capitalization then you will run into a very frustrating 'feature' than means CAPS lock is not turned off until it is fully released. This ends up with a lot of typing LOoking LIke THis. I can't help having learnt with caps lock as it works fine on Windows but there is no fix for Linux it's just something you have to get used to even though it is a well known problem going back for almost a decade!
Everything else is working, multiple monitors (two on this laptop), printer and scanner from the Brother printer (brother have excellent Linux support), webcam, usb sticks (Apart from exFat issue above), my usb phone tether, wireless mice, sound, videos, wired network.
I think Microsoft have really shot themselves in the foot with Windows 8. I've given Linux a try ever since the Ubuntu 8.04 days but there was always something that forced me back to Windows. This is the first time I think Linux is finally ready for the desktop.
