I am a gamer. It used to be that WINE worked 95% of the time 70% well, except on newest gamers. Nowadays, I can even run SC2 on WINE without much issue. Either way, to me, the newest games were never good enough to justify booting windows.
How-To Wiki? It's probably not what you want, but it's something....
Linux—the choice of a GNU generation
I started using Ubuntu in early 2009 (8.10, dual boot with XP at that time). It has been more than a year since I wiped Windows, and Ubuntu is the only operating system running in my notebook now.
I'm not really a gamer. Web programming activities is not a problem since Apache, PHP and MySQL are readily installable from the Software Center. For my digital artworks, Inkscape and GIMP do the job well.
Dual boot with 12.04 and XP 'cause my work requires me to access the same files as others in the office. Sometimes Calc will pollute the Excel files during translation and retranslation.
I would like to use linux solely but i need windows to run matlab for my college. So i run virtualbox with windows xp. I just can't get myself to getting used to octave, who knows perhaps when i have some spare time to set it up to my liking it is going to be ok.
I wish I could switch to Linux completely, I'm sick of Windows.
But I've got to keep it around for games and Rosetta Stone, mainly. (I can't get my mic to work!)
I think it's safe to say that most of us has something that binds us to Windows. I wish there was more support for mainstream retail applications
