I have a MOTO something or other. It's a killer for reception; mine works when other folks wish theirs did. I use Verizon, which helps.

I had a cheaper model before, and it didn't receive as well. Dont' go cheap; buy the best. If you need it for business, a Blackberry might work the best.

But I would strongly consider the advice about getting too connected. I know people who serve their bell phone/PDAs, and they are harsh task masters.

Sometime it's best to stop and smell the roses.
