Just a quick rewind. I think it was starboy that was talking about the feratures on the DS. I thought I'd confirm some stuff:

Nintendo DS
- Yes, it has wireless networking
- It has 2 screens, one being touch/pressure-sensitive
- The DS has 2 different CPU chips (I think an ARM-9 and an ARM-7), giving it processing power almost equivilent to the N64.
- I just saw today that Nintendo is going to offer a memory card adapter which will, get this, let you play MPEG-4 video and/or MP3 music. So, looking like, in a limited way, its going to soon gain the same functionality as the PSP.
- DS is backward-compatible with previous Gameboy games (articles I've read specifically say GBA games, but I have to think that GBC and GB games would also be counted in that).
