@TFG: If you're using micro-SD cards for local stuff then it means you're not streaming over Google Music, or storing your files in Google Drive, etc. A mate was showing off his recently purchases Nexus4, and sure it's pretty and swapping ROMs is a piece of piss but I'd want the extra space External can afford you. (though housemate has a OneX with about 28GB of space which is pretty damn big).
As for myself phone upgraded to Jellybean the other day. I've noted the new external file structure, managed to mess up QuickPic a bit, not fished through all my apps but likely PerfectViewer will need it's home folder changing too. Jelly Bean has pretty much fixed most of the issues I had with my Note. I'm quite happy so far, only complaint is the notification bar is now a dark shade of grey instead of the old black (the full notification shade is pure black). Nexus4 friend was also sharing a few Nova launcher tips with me too so getting a bit extra use from that (mainly the swipe actions, I tend not to bother with gesture based stuff, but this is simple enough to implement and also means I can combine Phone and Contacts app/button into one. Still figuring other uses. Multi-Window is a nice addition (yeah Touchwiz only, not strictly JB feature), though apart from the initial gimmick I've not made much use of it. Maybe something good to watch a longer Youtube video, say TotalBiscuit, while still browsing the web, facebook.
