Nowadays, I've found that I can install Ubuntu on more laptops and desktops and get better driver support from the initial install than even Windows can in many cases.
With Windows, I've had to scrounge around for drivers and pray they're compatible with Windows 8 Professional 64bit Premium Plus Bonus edition on the same laptops.
No official Google Drive[0] support (but we do have Dropbox)
No official Garmin Connect[1] support

Apart from that I totally have to agree with you - even the proprietary graphic card drivers haven't given me any real problems for the last 2 years.
But, again, all of this isn't much of an issue anymore.
(Also Google loves Linux and particularly Ubuntu. I'm not sure why they are dragging their feet on Google Drive but it's not because they don't care)
