I'm excited for it, and it's interesting to see the [admittedly cut-out] positive responses of other Android handset manufacturers.
It's early in the process still, but I'm already a little pessimistic about the prospect of eliminating Motoblur. Correct me if I'm wrong, but the proposed purchase would see Google operate MM as an independent company, and they would continue to license Android to them. I'm sure there will be more communication with Motorola than other handset manufacturers, but I wouldn't be surprised if we continue to see that damned Motoblur on their handsets.
But with any luck, Google will have them keep it off, and perhaps that'll make other handset makers take notice. It would certainly make it easy to recommend one widely-available Android phone over the others.
I'm still waiting for the Nexus Prime. If it exists, that'll be my next phone. And not a moment too soon, my Nexus One is starting to not do so well...
