I agree the performance is bad (heck my tablet just rebooted) but why not ready for Alpha? Alpha doesn't mean performance has to be good, and the application is (or will be) available for many platforms. Maybe they aim on OMAP3 usage, or bigger memory usage. Maybe debugging is enabled (it probably is).

What is really nice is that the layout adapts. So for example on Internettablettalk it ignores the black parts on the left and right and auto centers the middle. In MicroB I get a scrollbar instead. And the touch abilities are nice as well IMO.
