A question about cell phones.

[Poll #1752817]I'm curious how often people change cell phones. I've noticed some people seem to have a new phone every time I see them.  On the other hand I used my first cell phone for a decade before circumstances necessitated a change. I've had my current one since 2008 and I've been thinking lately it might be time to see if I can't get something better. Something that works decently in my house would be kind of nice.
