actually if you guys look at the price point it makes sense, how much is a 16gb mem stick huh???....... upwards of $100 compared to the 10$ umd drive, and i dont know if anyone has played an iso off of a mem card it is about 400x's faster than running off of a umd, specially dissidia and monster hunter, also any game you download you can run from up to 5 psp's simultaneously, so my gf and i can play monster hunter freedom unite together for 40$ compared to paying 80$ for 2 umds, also some of the games on there are 10-15$, and if you download them on a computer you can dl them in about 15 minutes and pause and resume the download.
Actually, to be fair, that is the consumer price. I can but one at Microcenter for around $60.00. What we pay at the store for a product, is not the manufacturing cost.
