i have one. but if emus were slightly better on psp i'd use that for a better joypad, and the power cord is not in your hand. i think battery time is about the same... i did use it for ages at one point. of course i had to pay £20 to get a custom firmware kit for psp just to run emus. i think the screen on gp2x is is better though. not so blurry? also i actually like umd movies. but alot of the ports like doom were lacking and blurry on psp perhaps i'll check for newer versions...
i am looking forward to pandora. i checked first to see where things were located it seems they have done a good job of locating ports to the right places. i won't have a problem with that. i am hoping real media will get some support. so i can just drag and drop films from movieflix.com. but it's not too much of a problem carrying around my jxd 301 just for real media movies. as long as i remember to put it in my pocket! just the one device would be slightly easier to remember i suppose.
the new eee pc is over £300 and is not worth the extra to me. yes a slightly higher screen res for web browsing but i think pandora too has advantages. i think emus and old skool gaming will be well supported. come on summer!
