Well, the thing itself sure does do a lot. However, IMO so many functions are kinda (Don't want to offend) useless. I wouldn't be angry if they decided to cut back on some features. to release it cheaper. I personally am only interested in the CF slot adapter (Because it has the cheapest flash cards if I want flash, and the only option for mobile hard drive cards, 4GB starting for 75 bucks. It also has an adapter for almost every other connection, be it Memory Stick [Regular, not Duo] or even USB) and secondly the power extending option. I'm under the impression that right now, USB 2.0 with large >4GB hard drives are nothing but a pipe dream. The PSP can only recognize so much memory at a time, perhaps because Sony does not see the worth in adding more since their Memory Stick Duos aren't expected to reach more than 4GB of storage any time soon.
In short, I feel like I'm paying $100 for something that does way too much.
