I have a PSP, no other portable system to compare it to. I have to say its one of the greatest things I have ever bought. It has a memory chip on it you can download pics, movies, MP3s and even GameEmulators to. Yes, you can play Nintendo games on it! The UMDs are great for when traveling, but you can buy software to convert your existing DVDs to the memory chip too. Theres not much of a game selection yet, and some of the games are very watered down versions of their console counterparts (Need For Speed:Most Wanted, Prince of Persia, Madden '06 for example). Others are just as good if not better than the console versions (X-Men Legends 2). This thing has been a lifesaver when stuck at airports or even on long drives. Listening to Beavis & Butthead Vol.1 made driving across texas alot easier :teeth:
