Has anyone considered the possibility, that since the Nexus One has the 2.1 software on it, that they might be concentrating their energies on making sure the bugs are ironed out for that device? I know it's not a Motoroal phone, but, perhaps the energy behind the software is being spent making sure that 2.1 runs in Google's flagship phone, before "older" devices are upgraded?
It makes business sense, in some ways. When you have a new product out that uses a version of something that is on an older product, the usual mindset is to concentrate on the new. Let's be honest, I have read a lot of complaints about the N1, but not too many substantial ones about the Droid, if our phone is running fairly well on 2.0.1, then perhaps Google is content to let the 2.1 for the Droid wait a bit while they concentrate on the Nexus One. Google/Motorola/VZW has some fairly satisfied customers with the Droid who would view 2.1 as gravy for their device, where as a frustrated N1 user might want his bugs taken care of, and taken care of now.
Just my .02.
