Since I took the plunge and bought it last night, here's my 20 hour synopsis on the GN2...
Its a big phone, or a tiny tablet, or both. I don't think I'll ever put it in my back pocket, especially sitting, so I'll use my junked Nokia with Straight Talk, if I really need a smaller 'phone'.
Reception seems really good (great technical term, yeah?) - at home I get my Airave 2.5 just fine at nearly full signal; on the road its as good as it can be if not better than my GNex and my old EVO4G. At work, however, it picks up 3G just fine if relatively close to the window, sometimes 4G is detected, but I building I work in is the recycled Montgomery Ward Catalog Warehouse, so it will kill most mobile coverage unless if you use a femtocell.
The only downside: Touchwiz. Its still as crappy as the older version on the T-Mobile Vibrant. But I'll learn to put up with it and shut up, and be happy with such a nice device.
