installed and tried... what I like most is the Mozilla Weave integration: http://www.flickr.com/photos/gbraad/4234868269/, http://www.flickr.com/photos/gbraad/4235651702/ and http://www.flickr.com/photos/gbraad/4242180327/. In the images it is shown running on the Maemo platform (N810 and screenshot of N900). The result is identical of course. The last image show that tabs are synced across systems. Besides this functionality it does NOT give any benefit above the standard MicroB browser (also Firefox-based). As soon the CouchDB (or Midgard) sync is integrated... or Mozilla Weave gets released as a MicroB extension, I see NO need to have it installed on my device.
