If anyone is wondering how the nexus 7 is for retro and modern gaming here is a video. its pretty awesome. I wish it had tvout though or maybe even mhl support. Oh well for now I will use a external case that folds into a stand.
Did you see the unboxing video collection on youtube? That was freaking HILARIOUS!
Anyways, nah. Bought a Samsung Galaxy Tab 7.0+(wifi only version, wanted a tablet from a REAL mfg and no hacked up Android, e.g. B&N, Fire, china tabs, etc.) on sale at an AWESOME price($250) a few months ago, so I'm done with tablets for a while. It's HC right now, but they're rolling out ICS(probably last we'll get) but it's only available in Austria(of all places!) ATM. (Next tablet & smartphone will be nexus though, but I'm going to hold out for hw updates before biting...)
(Probably think about a cheap Allwiner based tab IF they're really serious about helping out xbmc and others and run linux on it(well dual boot it), especially IF ARM does OSS their mali driver or makes it easier to integrate their BLOBs in kernel/X.org updates...)
JB has all sorts of improvements that are supposed to address latency problems with everything from the GUI(I never really noticed this unless I REALLY stressed my device) to sound and gfx.
