I installed iSwifter today. It seems buggy, and slow. Slow bugs do not make for fun use of the internets.
It appears to support multiple open tabs like Firefox. Yet the viewable screen size cuts in half when you open your second tab. And when this happens then I get intermittent response trying to move the page around to get to the links I want. No thanks to the idea of buying the app if it is going to work that way.
It does seem to play the GameTracker flash website I want but doesn't seem ready to be a paid app.
