I can also make phone calls with my desktop, laptop, and n800. If we're going by the criteria it can make calls then all of those are considered phones. I consider it more by use case. Yes, my desktop, laptop, n800, and N900 can make phone calls, but what's my primary use of those devices? Computer work, running applications found mostly on computers. Hence I consider them computers, and not phones. Granted your primary use of the N900 may indeed be a phone, and if that were the case I do think you should've picked another device because the N900 makes a poor phone outside of basic calling functionality. And I have recommended people away from the N900 who wanted more of a phone/smartphone devices rather than a computer/internet tablet.
