My first smartphone was the first and original droid back in late 2009. I had that one probably 10 or 11 months before getting the Droid 2 about 11 months later. That phone got messed up and they sent me a replacement, but it was Droid 2 Global. Terrible phone that I used for maybe 4 months until the HTC Thunderbolt came out in March, so I got that one and was pretty happy with it until November (so about 8 months later) when I got the Galaxy Nexus... which I've had since. So... Droid 1: 11 Months Droid 2: 1 Month Droid 2 Global: 4 Months HTC Thunderbolt: 8 Months Galaxy Nexus: 16 Months I've yet to go a full 2 years on a smartphone, but I think the Galaxy Nexus will be the first I'll go all the way with. Partially because I'm waiting for my contract to expire to switch carriers, but also in part because this phone is really great.
