Just wondering your thoughts on the these sleeves that I have found for my 15" MBP. I am going to college next year and have a NorthFace Recon Flash Backpack that has a laptop compartment. but this compartment isn't enough for my precious Apple laptop. So here are the three sleeves/gloves I was looking at. Overall, I just want to be able to stick in it in the sleeve and then into the laptop sleeve of the NF, so it really can't take up too much extra space. Also, I want it to protect the MBP from scratches, but also the more protection the better. finally, don't want the zippers coming in contact with the laptop... thanks! 1) The Radtech Rebound Series 2) The Radtech Glove Series-- What is the difference between these two? Rebound and Glove? 3) The inCase from Apple 4) The Vyper from Booq Thanks again!
