Higher's better.
I got a 9038 score on my device running microb, not even close to the 23,726 a nexus one got though. But, I feel I redeemed myself a little by scoring 405,393 on my workstation with Chrome (double what firefox managed, and 9x the speed of IE)
I got 18574 with mobile firefox (normal version, not a nightly) and the processor running @800 Mhz. Only contacts and mail in the background.
I'm sure somebody with some riskier overclocking, a nightly build of mobile firefox and nothing else running in the background can beat the nexus =) (just like in SunSpider ^_^).
