Query: Why are Treos so popular?

Utterly terrible reception (and I can't emphasize that strongly enough). I get "no service" in areas that I'd get four bars when using a phone that's $400 cheaper. I can't even get reception in my home! Owned it for two days, missed about a dozen calls. My guess is that you need to sit on top of a cell tower in order to make a call.Since there's no reception and it's useless as a phone, that makes this a $500+ PDA, which it clearly is not worth despite its pluses. That said, the software freezes and crashes often.Before I returned it to the Sprint store I sat in my car and checked the reception. It said "No Service." How Ironic.
