Most of us, I'm sure, are under contract and most us may have renewed contract once Note 2 came about. (I know I did.) Any who, I've been reading a lot about the Note 4 and it's speculated specs. I must say, I'm impressed. I was going to get the Note 3, but at the time I didn't really want the upgrade, nor needed it for that matter. My phone still works great, but now has a crack on it and the battery doesn't quite last as long. Doing frequent rom changes helps get rid of the clutter... lol.
Final verdict though, I think i will upgrade.
