Sony has a perfectly fine reputation. There are loads of people buying the PSP, what kind of power are you going to put into a budget system? We don't want to spend $2500 on our handhelds, do we? Sony delays releases? Well, lets look at Microsoft with Vista. There's another example right out of the box.
I've haven't played Vice City: Stories so I can't comment on how good it is, but those are just my thoughts.
