I am an Ubuntu user since 2004. Windows is used at work or in some specific cases. I'm not a gamer so this is not and issue for me. For the last 3 years, my work laptop was running Ubuntu to avoid the craziness of Vista. What was funny was that colleagues would come to me to fix their windows laptop using my Ubuntu cd.
But now that I have tasted apple products, next computer will probably be a Mac. Yep, they're not cheap, but you get what you pay for! Really impressed by the iPhone and iPad.
Seriously, thru all the gadgets/devices I bought, that's the first time I keep using and enjoying my iOS devices daily, even after a year and a half. Palm, PSP, electronics agenda, etc... They all lost my interest after a few months. But with iOS devices, they are just part of my daily routine as my phone, my tv, my fridge. I think I got spoiled.
