One of the more impressive demos shown at BlackBerry 10 Jam came from the folks at Xtreme Labs. Dave Protasowski, Principal Engineer and Sina Sojoodi, Principal, Product Development from Xtreme Labs showed off their Accuweather app using Cascades. In the video, they not only give a great look at the app but also show how simple the code can be to process and eventually push to the device in very little time. Check it out the video and drop some comments on what you think of it in action, to me -- this is what I've been waiting for from RIM. Fast, fluid and beautiful.
