My judgement of MicroB is based on my experience with it thus far (on the N800 and N810, with the latest software updates and all that jazz - I'm still *using* my N800, even if I've not participated here while doing so). It's also based on my other web browsing experiences, both on my various Symbian-powered devices (touch and non-touch) and on my laptops (including a few netbooks, such as the Fujitsu P1610, Dell Mini 9, and now Asus 1000HE). In contrast, microB is slower - significantly slower, regardless of where the site was designed for (full pages vs the custom tablet-only Maemo site, etc). It also doesn't synchronize with, well, anything, and struggles with Flash, specifically streaming media. It struggles with even sites like Google Reader.

@sjgadsby - thanks for the welcome.
