Help Needed with New Item

I have been thinking for quite some time that I should make laptop sleeves and totes. What I decided today was to make and sell them in sets. Since laptops come in all sizes now, I had no idea how big I should make them. Enter my Twitter friends! Thanks to their help and advice I have decided to make sets for iPads (since it was suggested they need a harder cover to protect the screen), a size for 10"-13" laptops and a size for 14"-17" laptops. Now, here's where it gets fun! What I need is exact measurements of the different sized laptops. I have a 17" laptop, so mine actually measures 15 1/2" wide x 11" high when closed. So, the favor I need is for you to measure your laptop (when closed) and let me know the measurements :) And if you also have any suggestions for options, etc for the sleeves and covers (such as pockets--make it padded, etc) please feel more than free to let me know! I want these to stand out from all the rest so anything you may add or suggest to make mine different will be very welcome advice! And who knows--maybe I'll just give one of these away :)
