Does a 249 PSP and a 299 PS3 go together?

The PSPgo is the premium version of the PSP, whereas the $299 PS3 would surely be the cheapest version available.
I don't see anything wrong with that, because there will be people giving a high value to the mobility that comes with the new form factor and not having to lug UMDs around.

The said "premium" version of the PSP has less functionality then the less expensive version, and has access to a smaller game library.  It is smaller and does have a smaller screen, so count that as a mix plus/minus.

Again, the premium value for the intended target is in its mobility. UMD aside, what functionality is it missing?

As for the library, I understand that Sony promised full availabilty for download of the whole PSP gamut of games.
