"An emulator would be no problem, as the StrongARM chips runs about 60x faster than the dragonball, so that emulation is likely to be faster than running native on the dragonball. Xscale would be 300x faster (assuming a linear increase in performance between StrongARM and Xscale based on MHz alone)." Your numbers are off. Dragonball currently tops at 33MHz, and while the ARM is likely to be more efficient than the Dragonball on a per instruction basis, a factor of 10 is way too high. The follow on to the SA1110 is going to have a top clock rate of 400MHz not 1GHz. So you are looking a 10x performance. Now ARMs are really good at emulations, but even so I would guess that 2-3 times greater than current Palms is the best you can expect. Less, maybe a lot less if Palm apps hit the hardware directly. I looked over PalmOS a couple of years ago with an eye to using it on a project so I don't know how the apps are written and if they go all the way to the hardware. We chose WinCE because the PalmOS problems were so severe. Now, of course, we are using Linux... And are better people for it.
