I bought from newegg.ca, and went through the RMA. After two weeks now, the second N8 is holding up great. The more I use this phone everyday, the more I like it.
Using Wind Mobile's network here in Vancouver, and getting great reception, and quite impressed by some of the 3G and 3.5G speeds I get.
The build quality of this device is more appreciated each day. It's like a fine piece of craftsmanship. I don't use a case, so I can appreciate the feel of the device. I really like the rounded edges. The front button is so subtle, and yet so precise in turning on the device, along with the nice single tap to unlock the screen. Even that sliding unlock/lock button on the side is very much appreciated.
The UI can be sluggish. Hopefully improved with the upcoming updates. I think the calendar/notes/contacts need a UI interface update. A simple app like Notes, does not even support kinetic scrolling.
