Also Opera has tab browsing, integrated keyboard which is better than FastSMSEvo at the moment and single touch zoom.
I was under the impression MicroB was closed source? Hence why no changes have been made to it (like mouse support).
MicroB is firefox based and just as firefox is supports add-ons MicroB got alot of potential I'm still confused why no one have made anything usefull for it yet.
...and tabbed browsing, single click zoom which is very handy , keyboard which suprisingly is very good, better way of copy paste
