Although I have pretty much always had one, I have never really cared much for the functionality of a cellphone, other than what it was meant to do...like placing phonecalls. I have an uninteresting Motorola Rzr, so anything is pretty much an upgrade.
So I decide to get a new phone. Windows Mobile? no thanks. I have had experience with a couple of pda's and until Microsoft comes out with something completely new, I will not go through that again...iPhone? no thanks... and although I have an open mind to maybe sometime try anything that Apple makes, it seems that everyone has one and I would have to switch providers.
What else...: Google Android...? all my Google apps constantly synchronized? Built-in GPS and Google Maps...? Unlimited Internet via 3G in my area? I now understand what is so interesting about a smart phone. The amount of productive apps that are available, the variety of functions they can performs is impressive, especially the location-aware applications. The one drawback is that if I ever want to write an application for it, I am going to need to learn some Android OS and Java.
Other than that, I have had it for only a couple of days and really love it...
