I prefer the PS, I've tried the Wii and the games are not mentally challenging. Xbox just seemed like MS trying to get a piece of the pie. PS3 currently used for gaming and streaming from local network to HDMI on TV.
For Computers I prefer MS over Apple. Never liked their MAC software, always found Windows easier to work with. (I did like that all the programs were single files rather than components, but this made them harder to diagnose when a program crashed.). Android for phones, Apple's a rip off (lower quality, less functions, and costs more), and windows doesn't do touch screens well (haven't tried 8 yet).
