Well, my situation is somewhat different than most people I guess. Having the only audio output be over HDMI is a deal breaker for me, since I need an optical out (or even a fucking headphone jack) in the spot I want to put it.
Also, I don't see anything about a 1080p update for the PSTV itself and I think it's still 720p/1080i only. Are you maybe confusing that with the PS4 firmware update from a while back that allows for 1080p Remote Play? AFAIK that's only for compatibility with Sony phones and the PC Remote Play client, but I'm not 100% on that. Vita resolution is only 960x544 so it doesn't really matter much for Vita games, it just means it's shitty for anything else. I've heard Remote Play has lag problems on it anyway, plus there's no apps for Netflix, Amazon Video, Spotify, etc. (read: Hulu Plus is about all there is and probably ever will be). Bottom line, it plays Vita games--and that's "most" not "all"--and that's it. If you want a set top box for streaming, you still need to buy a FireTV or whatever.
It's only like $40 though, so I could deal with it being useless for anything besides playing Vita games if it weren't for the audio issue I have. Working around that would involve buying a second ~$30 box, and at that point I'd rather just pay the difference and have a Vita.
Sony are still charging a retarded amount for their stupid proprietary memory cards too, which imo was one of the main reasons Vita failed so miserably to begin with. It makes me not want to buy one just on general principles.
