While browsing the Android Market last night and reading inconsistent reviews about a lot of apps having/not having issues with the Moto Droid, this leads me to ask: are all Droids built the same? Software issues aside (OS ver, app conflicts, etc.) there is still the possibility that not each of the million+ Droids out there are running identical hardware.
In the PC realm it is very common for hardware manufacturers to make stealth modifications/fixes/upgrades/downgrades to a piece of hardware without ever announcing it. I am sure it happens in the mobile space too. I am willing to bet the Droids rolling off the line now are not the same Droids that hit in November.
