My point still stands you can't measure usability with any micro-benchmark and when it comes down to it that's all most people care about on a mobile device. Mobility means a very complex juggling act where any 1 new feature may make or break the device ( sure you can watch 800x480 videos, but if it's only good for an hour that would suck ).

Having more mips/watt than your competitor will place you at an advantage in terms of what you can do, but it's no match for usable features. My Palm IIIc has an order of magnitude difference in computing power to the n810 and yet it could still run circles around any NIT PIM today.

So measure all you want, but the real benchmark is user uptake and satisfaction.
