1) Dual screens with seperate information on both, giving greater variety and depth to DS games. Yes, PSP has a larger screen, but, boy, does it eat up that battery twice as fast as the 10 hour ds battery. And watch those movies on a PSP. They will bring battery life down to 3 hours. 2) Touch screen. Truly a fantastic, innovative feature that PSP cannot rival. New games such as Kirby's Canvas (perhaps the best portable game ever - Imagine playing Sonic the HedgeHog, yet, you draw your own screens!) and METEOS (Tetris x 1000 with a sylus!) are better than any games on the PSP. 3) Wifi built in. Yes, so it's on the PSP too, but. imagine playing classic Nintendo Games like the upcoming Mario Kart (which is rumeroed to have every Mario Kart game on it) and playing this with persons online anywhere in the world. 4) Oh, it plays over 1,000 Game Boy Advance games, many of which are worlds better than PSP games (check out Advanced Wars or Zelda Minish Cap). 5) Yes, the price: $149.99 (vs $249.99 for PSP) with a $30 game, Super Mario 64, perhaps the best platformer game ever created. Most PSP Games are $39.99 while DS games are $29.99 (wait until Nintendogs comes out....an amazing , innovative game). Now, some of you are going to say "The PSP has an MP3 player and you can watch movies". To that I say: In order to truly download song/movies, you will need to by a $100(!) memory stick. ANd, oh, let's not forget that serious draining battery. Cant plays games and listen to music and lwatch movies if that batter doesn't last long. Put the $100 toward a NOMAD Video/Mp3 player with TV like features. THe future catalog for DS looks quite amazing, which is expected of Nintendo, the true innovators of video games.
