Without having ever actually touched an N900, I still think the statement "It's not a phone" is wrong. Of _course_ it's a phone. It's just that the phone aspect may be overshadowed somewhat by the fact that this phone is also a mobile computer, sometimes called an Internet Tablet. But it's not really the Tablet either, because the screen is smaller.

Maybe some of the phone functions are limited (depending on what you want to use it for - no MMS means nothing to me, for example. It's not what I'm looking for in a phone.) - but missing/limited functionality will almost certainly be added, after all the hardware is there to do it. So, will it then suddenly be a phone? I would say it's one already.
