I have a Storm (have connections in RIM) and have been using it on the Rogers network for a few weeks now. It will only be available on Telus and Bell in Canada, (although it supports GSM networks so they can use it in Europe.) It's not as great as previous Blackberries, the touch screen does leave a lot to be desired (no where near the iphone one). Some features are great, some not so great. Overall, if you want to get a Blackberry, I'd recommend a Curve or the Bold. They are faster, easier to type on, smaller and lighter, but the screens are smaller so not as great for web browsing or watching videos.
For what it's worth, I also love my Pearl, and might switch back. It's less expensive, and if you are not a heavy heavy email user, it's perfect. The only reason it's more of a consumer device, not business, is because of the condensed keyboard and smaller screen.
