Does the newer Sony remote still turn the PS3 on with any button, or just the PS button? That's my one gripe with the original remote.. I accidentally bump it and the PS3 turns on.
Just keep in mind that the Vita carts still install to the memory card. IIRC, Uncharted installs about 2 gigs of data.. I have an 8GB with my 3g kit and wish I had a 32..
B&M Target stores seem to have PS Vita AC Adapters and USB cables on clearance for $10.49. I confirmed at my local stores and my friend in another state confirmed he saw them there as well.
A pretty good buy for anyone who wants an extra cable for travel.
