Id probably buy a Psp- 3000 over a Psp go. No physical media and its 80 bucks over a Psp - 3000. I like the Psp - 3000 more than the DSi since it has better multimedia options. Games like dissidia, monster hunter, Crisis core,MGS: PO and Peacemaker are only on the psp so yeah. Only games i can see on DS that really appeals to me is Pokemon because i love the series, the world ends with you and the new KH DS, but i like the PSP version better.
The Psp Go looks like a big rip off in my opinion. Cost is too high, smaller screen, and again no UMD option. Atleast they could is have an option to install a UMD into the psp go's flash memoryfrom an adapter that hooks up to the psp for installation for the high price it has.
