Frankly, I'm a bit surprised (pleased) about a couple of things.
First, the promptness of the upgrade by Motorola and Verizon reinforces my admiration for the stability and excellent design of the Android O/S. I doubt that very many folks here have been involved in implementing major software upgrades, especially for an operating system, but it's not a simple task, especially for a particular hardware platform. Having 2.1 ready for the Droid only a few weeks after it was released from Google is quite an accomplishment.
Second, it appears that Motorola (at least) plans to be somewhat more transparent in their upgrade plans. That, too, is welcome news and, again, it's not something a vendor undertakes lightly since it can often raise more problems for a vendor than it solves. It doesn't fully resolve issues of rumors built on rumors since upgrades by Motorola don't necessarily mean upgrades by Verizon but it's a good start.
