Pretty much everything that's not literally playing games is disappointing. Yeah, it has a browser and Google Maps, but guaranteed, if you have a smartphone made in the last three years, your phone is better at both those tasks. (There's no email app, either, and the browser doesn't support any kind of video, not even YouTube.) The on-screen touch keyboard is especially annoying to use, since you have to reach your thumbs over the PlayStation buttons to hit the screen. The back touch panel is gimmicky; only a few games support it, and I found it very uncomfortable to use without accidentally hitting it, and not especially fun besides. (The exception is in FIFA, where the location you tap on the back panel corresponds to which part of the goal you're aiming at. Still uncomfortable to hold, but very effective.) There are some oddities in the OS, like the weirdness of having to tap twice to go into any game or app (once to open the thumbnail, another to actually launch it. Why? No idea.) And the speakers are surprisingly timid, volume-wise.
