I have a storm and like it. You can do anything you want on it. The internet is better than on any other blackberry device and the 8 gig memory card that comes with it is a plus. You can put all sorts of music and full movies on a storm. The screen is good size to be able to watch those movies as well.
The Voyager is not made anymore and was replaced by the envy touch like previously stated. The only problem I have with the touch is that the "full QWERTY" key board is set up crappy and hard to use IMO.
As far as the storm breaking pay the $6.99/MO so if you break it they will replace it. All Blackberrys come with a 1 year warranty out of the box so if it breaks within a year Verizon will replace it. Replacing broken phones is not the big issue it used to be.
Also the best thing about Blackberry devices is that you can back your whole phone up on your computer. Pictures, text messages, call log, ring tones, phone book, everything. So if your phone breaks and you have it backed up on you computer you can go get your new phone and just plug it into your computer and it's like your never even got a new phone.
Ok that was a lot I am just a fan of Verizon customer service and Blackberry phones. Neither have ever done me wrong.
