I agree that the device was a disappointment. I was hoping it would be a revival of the Nokia N900 spirit, but the poor battery life, the lack of a decent hardware keyboard at launch, plus a change in the FOSS development culture, just meant that it never attracted that critical mass of hackers.

The unresponsiveness of the browser seems all down to the very underpowerered A64 processor plus slow memory. With those hardware constraints, I'm not sure the community could have come up with any solution.
