Oh I forgot.



Better IO scores I believe is thanks to the fact that HTC decided to to with ext3 partition for its OS, thus having faster read/writes(I'm not sure about this.. I think its thanks to the ext3 partition)



Also yeah, like I said, the CPU architecture is similar, (very similar actually), just the overall application processing is better due to tweaks, and one guy mentioned hardware flash acceleration which I forgot to mention, and obviously the GPU. Basically its a very well refined package of the Snapdragons that were on the N1/Desire.



Next year's 3rd Gen Snapdragons will be dual core Scorpion CPU's, even better tweaking and optimization, and HUGE gpu improvement.

Qualcomm says that Adreno 220 is 4-5 times faster than Adreno 205.
