In this video, I illustrate how strong the magnets are in the Smart Covers for the iPad 2. His iPad is on the way from Hong Kong, but his cover is here right now.

You’ll be surprised at how well the cover sticks to the fridge. Giving a light tug just isn’t enough to dislodge the magnets in this cover. If you want to get the cover off of something, you’re going to need to give it a good yank. After having played with it, I’m thoroughly convinced I’ll have no problems with this coming off of my iPad while in my backpack.

As far as the polyurethane goes, it feels strong. You’re not going to have to worry about cracking under normal conditions. It really does feel right in your hands. If you’re not a fan of the leather covers, you’ll be very pleased with the polyurethane versions.
