...and that's why PSP Go is best.
Not entirely kidding.
PSP Go has some real issues. Having cramped controls is one issue, especially problematic if you have large hands. The wireless access kind of sucks - although I suspect that's common for all PSP models. Most notably: being limited to PSN Store for games is another issue - it limits your selection, prevents buying cheap or used physical copies, and ongoing accessibility is a question (link:

However, the little console also has some advantages over other versions of the platform. PSP Go is wonderfully portable - smaller than anything else I've played other than a GBA Micro. Pricing with PSN sales is good if you can wait for sales, and if you've been a PS+ member then you might find a cache of games just waiting for you to download anyway. The screen is better than PSP-3000, the system has bluetooth so that you can sync a headset or real controller, and the TV out options are better too. The sleep function when you slide the screen closed is also awesome.
PSP Go totally
wasn't worth the high initial asking price. But when the systems were getting cleared out for bargain prices you could easily grab one for $50 or less - and accessories (charging cables, TV cables, docks, cases, etc) were all available for a pittance. If you see one cheap, and if you don't mind going all digital for games, it's worth checking out.
