I wouldn't gloat too much as someone will surely find a way overclocking the snapdragon in the Nexus.
I thought they already had, if so it would be interesting to see what they can get it up to, but regardless for me this is the best device in the world, im completely new to all this, ive had my n900 for about 3 months now and have loved learning how to do new things with it almost every day. N900 Rocks
A friend of mine just ran the test on his iPhone 3GS (in Safari) and got a score somewhere in the 24000 range, so I wouldn't know where the comparison results are coming from... (He also tried in Opera Mini but couldn't get the test to load there).
I got 8500 in MicroB and 21834 in Midori, both scores @ stock 600MHz, no other apps (apart from some daemons) running
Edit: I just ran the test twice on my iPod (3G) and both times got a result in the 25500 range, so there's definitely something off with the comparison results (N900 still rocks though ^^)
