Phew, the screen size issue was debated to death some time ago, and yeah it was also said that the Tablet format was gone in favor for Smartphone one.

I remember being commented that the new size was thought as the non-full screen mode of current apps in current tablets. Start your app, do not maximize it, and that's the size you were getting.

Despite everything, the N900, from the official web page "a high-performance mobile computer with a powerful processor, large internal storage, and sharp touch-screen display."

Now, if you say "inferior" because it is resistive, well, that is not the case. Resistive has been adopted because the user cases for the N900 see it suitable; AND reports from people that has actually used the tablet mention it as very sensitive (at the point they couldn't guess if it was capacitive or not) and that the UI has been designed in such a way that the use of a stylus is not needed (but it is there if you want/need it).
