I got my 1520 back around March I think, and it's been almost flawless. I upgraded from my 920, which IMHO it still a great phone. So far the only issues I've come across have to do with rare data lag. I'll be using WiFi or regular cell data and have full bars, but for some reason it doesn't want to load a page in IE. Rebooting the phone usually fixes it. I've noticed the sensitivity problem, but it hasn't really been that big of an issue for me. By comparison, it's slightly more sensitive than my 920 was. I've just gotten used to using a lighter touch and I try to avoid links or buttons when scrolling so I don't accidentally open anything.
