Mostly the cost difference and the convenience.

Well, you can go to Radio Shack and get a very nice two line GE phone with caller ID, speakerphone, and a bunch of other features for about fifty dollars. I just got one because I'm going to have two different VOIP services at my new place in NC for a while. When I have the bucks, I'm going to get another one, too.
I used to be leary of phones being sold by Radio Shack. But what I've seen there lately has been an improvement. It used to be off brands. But now there's not so many different model phones but a few good ones insteads.
