I recently joined the smartphone bandwagon and got a Droid X. So far I have been impressed with the functionality of the phone in general and with the Google integration of the Android in particular. Since I already use Google for my email, calendar, and tasks it was simplicity to set those on my phone.
I have to admit that while I tend to view technology as a tool, having a smartphone is also a neat gadget. I do primarily use it as a tool, but there are fun things like games and such that also make it fun. Plus, for the geek in me it is very tricorder-like.
