I have a D3100, and love it for the lightness, and small size which fits comfortable in hand. You'll know what I mean if you carry one around all day long being a tourist and whatnot. The D90 was just too big for me, as D7000 probably would've been.
Hope this helps.
1. Meh, not sure which two you're comparing. Canon has bodies that feel both cheap and great, just as Nikon does. There is no one standard "Canon" template.
2. You get used to it. I thought the same thing when I got my 50D moving up from my Rebel XTi/400D, but I got used to it. Now I can carry my camera all day without any issues with the weight. A good strap definitely does help though, and I swear by my Crumpler Industry Disgrace.
