Go to the store and try them out. I have the storm and am waiting for the niagara to be released since I prefer the qwerty keyboard. You have to get used to the storm and be able to handle the pressing down of the entire screen. This is something that gets to me since I feel like I have to do a lot of work to type even simple things. Same thing goes for when I'm on e-mail and when I try to click on a link it just zooms in.
