The difference is that the N900 has a better screen than the N8. The resolution, AFAIK, with the N900 will enable you too see smaller text and have more on a screen as opposed to scrolling around to get a full page view. That means the screen is 'smaller' in the N8. The N8 might have a capacitive screen vs. resistive screen in the N900 but as far as which one is better is a matter of opinion. I can say that the N900 seemed to be pretty accurate and I prefer it(screen) to the Nexus One with a capacitive screen that is barely usuable in sunlight.
