One disadvantage of microb, at least for me, is that it doesn't handle USB mouse clicks; I can point but I can't click. Opera can handle that, as can Chromium (under Estel's Easy Debian).

EDIT microb doesn't handle clicks on the links, but clicking on the buttons in the browser interface, e.g. the back button, works. One exception is the maximize button in the lower right corner, that still needs a fingerstylus tap unless the address bar is visible.
