I got my N1 about a month ago from Amazon. It's a good telephone. I only use wi-fi for internet. The build quality is excellent. I expect it to last for years. I'm confident it will be updated into the future. Haven't had a single problem with the phone or operating system. I bought it because the price was right($283). Inexpensive for a handheld this powerful.
It's "just worked" for me.
Hope this helps,
