acer dual-atom (2gb ram, 10", 240gb)... mine is rounding 2 years and can still be my primary pc (though it isn't). it's down to about $220 now.
it's perfect for email, browsing (use chrome, very noticeable difference on a netbook), office apps, and playing songs/videos. and of course, retro games! i think they've included hdmi out now also. the battery's fine, and pretty cheap/easy to get a 2nd
