The maemo 4 version seems to have a bit more polish than the maemo 5 version. Rotation works great (automatically rotating the whole OS?! madness. For those curious, it does almost the exact same thing sliderotate does), detection of hardware keyboard, and it doesn't pin the CPU when idle (but it has a memory footprint twice that of [maemo 4] microb when just navigating to maemo.org) .

Not as innovative as Fennec, but considerably faster. In my 20 minute test, my one complaint is that google reader doesn't work (ajax?). A modern, usable browser on the n8X0 devices. Tear may be faster, but, at least for the moment, I am swooned by the smoothness of the UI, zooming, scrolling, TABS, so much to love.
