Bought one two years ago - Ye Olde FAT beasts
Used otheros & linux to rip a few bluray movies ... got bored, too slow (ever transfer 40GB's across a network?), ... so now I just use to play games occasionally, and as a media center (inc Bluray- YAY!!!).
And bought my parents one, 9 months ago - they just use it as a bluray play, and media center.
