With the Droid 3 BOGO promotion (@ for $149), I upgraded from an OG Droid and my wife from an LG EVY 3 to Droid 3s about 7 weeks ago. Mine would not complete activation and was immediately replaced. There have been no problems with the 2nd one and my wife has had no problems with hers. I went this route as I could not justify the expense of getting the Bionic for me @ $299 and spending another $150-$200 for her. (These were the prices in late August 2011).
My wife is very pleased with hers. She is using the laptop less and less and using the web and social media apps, Facebook and Twitter, on the Droid 3 more and more.
I thought I would miss the 4G, but in looking back, I have not. While home, I am connected to my home network and while traveling, I have connected to hotel networks, airport networks (when free), library networks, MacDonalds, Panera Bread, Starbucks, etc, and client networks. I seem to nearly always have a high-speed connection.
Neither phone has mysteriously rebooted. My phone is rooted, but no apps are frozen or deleted, and my wife's is not. She is pleased with the stock Home Screen/Launcher and I am running "Go Launcher EX".
Battery life, has improved with the update and we consider it acceptable. We both are usually able to get the entire day out of an overnight charge.
We have no issues with the screen, we find it very clear and bright.
Just my opinions here, your may differ.
