For a very short time that we can use Google Chrome, known as Chromium for our Nokia N900, and now we can install many extensions to work even better 
.
There are some extensions that do not work, but many do. I have served the extensions Gmail and Google Reader. Also i recommend FlashPlus with which we can manage the Flash content of the pages you visit.

Seems very buggy still and full of desktop keyboard features which don’t work on the N900.
Can only input in capitals in search field.
No easy way to zoom (Ctrl Fn + or -).
Full screen switchable only by menu and then it’s stuck there (there is no F11 on the N900 keyboard!)
Cannot scroll by touching screen and flicking, only by scroll bars.
Display errors in Options screen; overlayed text.
Still can’t better the MicroB browser.
