The good news come from Germany, where some users have reported that the 300 MB OTA update has kindly asked them to be downloaded. So far, there's no info about other countries, but if Germany is getting it now, then more are sure to follow. There aren't too many details as to exactly what new stuff the update's bringing, but sweet goodies like Project Butter and Google Now are 100% featured.
The Samsung Galaxy Note 10.1 is a 10.1" tablet with very good hardware and an S Pen stylus with pressure sensitivity. It's biggest downfall is its screen resolution, which is 1280 x 800 pixels, translating into a pixel density of 149 ppi. If that doesn't bother you too much, though, you'll probably find using the Note 10.1 quite satisfying.
