Mine's the best phone I've ever had (I have the Motorola version). It's the first phone with which I could actually go on the internet, and with the Yahoo Mail, Facebook and eBay widgets, it's quicker and easier for me to go check something with the Droid, than sitting down and going on my laptop. Although I'm a big Apple fan for quality and reliability reasons, I never got an iPhone due to some limitations it has, such as problems picture messaging people who don't have another iPhone, etc.
There are three things that the Motorola Droid could improve: Battery behavior, micro-SD card is inconvenient to remove & reinstall, and poor phone voice quality. The batteries have a mind of their own, and sometimes last 3 hours or sometimes 2 days. It's more than just how many apps are open, or how much talking. It's something weird about the battery charge indicator circuit. And the voice quality sounds kind of like the astronauts on the space shuttle talking over the radio, but I'll put up with those problems since the rest of the phone is outstanding!
It's saving me a fair amount of money in things I used to have to pay for elsewhere, such as the traffic maps. I had a device called the TrafficGauge, which is leased from the State of California for $100/year. I canceled that, and I'm going to cancel my USB internet broadband card, which I used for my Netbook at $70/month.
And one more concern: I haven't dropped it YET. It has a large LCD screen, and I have the feeling that it won't survive much of any impact. It's insured, but still I don't want to break it.
