What's so special about Nexus One??!!! Seriously??!! For starter it's the first phone that is actually being produced with Google as the backer. Follow that up with a 1Ghz Snapdragon processor compared to the 550mhz Cortex A8 in the Droid and an AMOLED screen.
dont let the numbers fool you.... the snapdragon 1ghz isnt much if any faster then the cortex a8 550mhz.
The current Snapdragons that clock over 600Mhz are definitively based on Cortex A8 cores. Qualcomm was able to get an architecture license from ARM. So the 1ghz snapdragon is almost identical to the Cortex A8 except they have added more pipeline stages to get the extra clock speed. From what i understand the cache size is identical in both chips.
