The GSMArena test has a big mistake - it says MicroB can reflow text when zooming a web page. Well it can't. The undocumented Ctrl+Shift+I workaround does not give results for most pages.

Android browsers can reflow text no matter how many time you zoom in.

The lack of this feature makes MicroB pretty useless in the long run.

BTW, same applies to Firefox for Maemo where you only have two zoom levels anyway.
