I own a total of 5 PSP's spanning from the PSP-1000 to the PSPgo and would have to say the PSPgo would be my favourite of them all.
Whilst I would agree that it isn't everyone's cup of tea it is quite a nice improvement on previous models. Before owning a PSPgo I was just like most of the others who are against it and the system since I didn't really see the point in it.
But after actually owning it for a while I have grown quite attached to it with it's smaller size (now I can put it in my pocket) and other functionality (bluetooth, 16GB internal storage, pause game feature, full-screen clock/calendar) is a great addition.
I think the main problem people see with it is the lack of UMD support. For new PSP owners this doesn't really seem like an issue to me though and in-fact downloads do have their advantages over UMD offerings:
- The games can be played on 5 PSP's simultaneously, PS1/mini purchases even work on the PS3.
- No need to carry around any additional physical media to play the games.
- Many new PSP games come with digital user manuals so you can read up about the game on the PSP itself.
- The games have a good possibility of being playable on the NGP without a need to re-purchase.
Sony didn't take the necessary steps to support the PSPgo however such as offering a UMD for download redemption program, competitive pricing and variety in available content. Though they are catching up in some respects to the last 2 problems which is great to see.
