I like to use them for help on picking things out. Granted it is just telling you how to pick the right cell phone for you:
CR: Cell PhonesHere is something from Verizon:
ReviewNow me personally I dislike the fact that with iPhone or practically all Apple products they have there own apps and are very very uncompatible with other platforms. For example the music you have to go the Apple Store or iTunes and you can't download from other places to the Apple network which I guess would be better to fight off viruses, but I dislike being controlled in that aspect.
For the Android they have excellent capabilities and are able to go on other platforms and I don't like Verizon for a provider, but still the Android Market is ever growing and pretty decent and a worthy contender with the iPhone.
Finally and not lastly, but the Blackberry is like a mini computer and I think it handles multiple platforms in an excellent fashion and well it's the best of all the worlds. Sleek, slim and wonderful.
