I don't want to add a "me too" comment but I'm a true story of failed Linux Migration.
I deleted everything on my home computer and moved to Suse (my first time exposure).
I was in awe of the interface and the wealth of customization available for the interface.
But...I'm an avid gamer and couldn't:
1- Get my ATI Radeon 9700 Pro work flawlessly with the computer.
2- Get wine to play games.
3- Couldn't find my fav titles for Linux. Quake 3 is a bit too old now. :)
But worry not, an old PC is now a perm Linux machine AND an additional hardrive gives me the linux exposure.
Get games to work on Linux I would switch in a heart beat! I kid you not.
