I saw the iBallz folks at MacWorld last year, when, true to their name, they were displaying their products guerilla-marketing style... No booth, but showing their products to anyone who would give them a chance. What a difference a year makes, as they had a serious booth at CES and will also be there, officially, at MacWorld.
So what does iBallz do? They have a novel approach to keeping your iPad safe. Instead of trying to cover the glass, they use specialized racquetball-size balls on each corner with a bungee cord connecting them. The end result is that the tablet is protected from just about any drop, and iBallz loves to demonstrate that fact over and over!
You can even use the cord to carry the tablet or mount it on the wall!
This year, they have expanded to include support for 7" tablets, and they offer hard and soft cases that accommodate the tablet with the iBallz attached. As a mature product, you can now order the iBallz with multiple colors (black, gray, pink and teal) as well!
