Opera Mobile has tabbed browsing and opera link (like sync) since almost a year ago and it΄s bloody fast. And it's a beta still since it was a weekend project from the opera guys (I shudder to think what it could do if it was a fully backed project).
Why can't Mozilla get a half decent browser out with so many developers working at it and beta's upon beta's is troubling.
Come on guys microB is much faster (even if lacking in the UI department) and it's Firefox based.
I for one have stopped expecting anything decent from Mozilla (at least for the N900 and Maemo). It's the same as Android's. It's going to need an 1.5 GHz CPU just to run smoothly.
We used to curse Microsoft, Adobe and other developers that made our new hardware obsolete with their bloated software, now it's the mobile Os's and applications turn.
Back to the drawing board guys, you should get some lessons on mobile applications from Opera, Rovio and many guys from maemo.org.
