Jardenix; I've been using the N900 as a regular phone for over 3 months and I'm pleased with it so far.

I feel you'll need to overcome the form factor first, since it's what most people will notice and comment. If you like it, then under the hood, is a powerful device (if you know how to tinker around).

As a regular phone - call quality, functions, etc, it's 'above average' performance (my personal feeling). I may have chosen the E7 over the N900 if they were both available at the same time - because I only need a regular smartphone. Still, the N900 will be a keeper. Plus, if you can still get it now, I'm sure it'll come with a good discount since it's considered 'obsolete' product.

Hope this helps.
