DS! Or not?

Okay I've got ten minutes to decide
BUY A DS WITH DRILL SPIRITS (and mario later)
or
NOT?
Any replies made to this thread will in no way influence my decision.

1. Assuming you never, ever update your PSP (anything past 1.5 can NOT play emulation).

2. Or maybe, just maybe, people prefer the DS. People who CAN afford the PSP don't seem to be buying Grand Theft Auto: LCS more than Mario Kart DS (650,000 non-bundle sales, 350,000 bundle sales, compared to 750,000+ for LCS), with MKDS selling more in a shorter period of time.
