SA, 4chan, and YTMND all steal shit from each other. Then it spreads all over the internet from their retarded members posting stupid phrases on place like youtube, online games (WoW), etc.
Everytime I hear something like "i heard you like mudkips" I think mentally and socially handicapped 12 year olds. Is if "PWNED!!!1!!" and 1337 speak internet culture wasn't retarded enough.
Both are awesome handhelds, but I say PSP. Some of its games are just too good for a handheld IMO (like Syphon Filter: LS, Daxter, R&C: Size Matters, Tekken 5: DR, etc.). I might give the DS a slight edge in future lineup though.
I like the look of both and both have their advantages:
PSP - Generally has better games and more features that pwn
NDS - You can buy an R4 card that you can just put emu roms on and play them like your DS is an emulator. Saves lots of money. Obviously you only play games that aren't copyrighted :S
