I find its always helpful to compare the hardware, as well as the software (OS + apps) of devices I'm evaluating. So in addition the very-good-so-far iPhone and N900 data points, I would also offer the following:

1. Both phones utilize same underlying CPU Core chip (different from CPU itself): ARM Cortex-A8
2. Both have same RAM capacity: 256Megs
3. Both have same graphics controller: PowerVR SGX
4. N900 has considerably more user RAM: 3Gig versus 0
5. N900 has higer pixel-depth of iPHONE 3GS: 800X480 versus 3200X400

The iPhone out-strips pretty much all WinMo phones on the market today, but FTW the N900 matches or surpasses the iPhone in critical compenentry. Details: http://pdadb.net/index.php?m=pdacomp...=2019&id2=1938
