well the 4'' inch screen and higher resolution makes webpages easier to view on the x10, but the browser itself isnt as good as microb. The one on android is webkit, im pretty sure microb is not webkit, so its better as a browser. The x10 browser (which is called google chrome by the way) doesnt have flash either, but it will come in the 2.x update (in Q3 or Q4). So the point is, if the X10 had microb, it would be the best mobile browser. N900 has the better browser, but the X10 has the better display, so I guess its just a matter of opinion. There both fast by the way, I like the google chrome because a lot of webpages are optimized to work on it, on the n900 you have no choice but to view the full desktop version, which is both an advantage and a disadvantage (for example, try viewing facebook on the N900)
