I picked up my Vita today along with my free copy of Wipeout 2048 and the free case, though sadly my 32 GB memory card did NOT arrive. I have a 4 GB card that came with something else I picked up, so I'll be good for a little while but unfortunately that means I can't transfer all my PSP games over yet. I'll probably have to pick 1 and hope for the best over my vacation. I'm really happy with how well my screen protector sheet went on, thanks to the guide it was attached to initially. There's a sliver of the screen that's uncovered, but it's a corner I'm not likely to ever use and I already got the cover on with no bubbles so I can live with it. If it weren't for that little sliver of uncovered screen, you wouldn't even be able to tell at a glance that there is a protective cover over it.
From a sheer hardware standpoint, I'm really liking the Vita. The OS feels pretty user-friendly, and a lot of the obnoxious bugs reported at launch seem to have been fixed. For instance, the issue where it want you to download a firmware update before you could link your PSN account has been fixed. Like the PSP, the Vita also came with a handy startup guide, so figuring out how to get started was easy. The device's online functionality also seems waaay faster than the PS3's, perplexingly. It downloads updates much faster, and it seems to transfer data much faster as well.
My biggest complaint so far is that the Vita REALLY doesn't want you actually opening its panels. You really have to force them open, which wouldn't be such a big deal if it was only the memory card slot but this is also true for the Vita game card slot as well. I'm also really not a fan of the way Sony forces you to transfer data between the PS3 and Vita. Before I bought the Vita, I redownloaded all my old PSP games and the few Vita digital games I own and left them on the XMB ready for transfer. With the PSP, you could select that file on the PS3 and then tell the OS to install it on the PSP. It would then ask you whether you wanted to keep the data on the PS3 or not after the copy is finished. With the Vita, though, you have to log into your PSN account on the PS3, hook the two devices up, and THEN use the Vita to select the things you want to transfer over. Then the Vita automatically deletes everything from the PS3 that it installs on the Vita. This wouldn't annoy me so much if I didn't know that I'm going to have to do this all over again once my 32 GB card arrives, so that means redownloading to my PS3 anything I put on this 4 GB card (unless I can back-up applications along with save data).
On the plus side, at least my Vita can actually access my home's online connection on its own. My PSP lacked the technical ability to access my network through my network security.
I'm currently waiting on some games to transfer over to my Vita, but I'm looking forward to playing some Escape Plan soon followed by some Uncharted and Lumines.
