I'm planning to buy a Booq Taipan skin for my 13" MBP. I hesitate between the S and XS models. The XS is said to be compatible with MBA and MBP, but at the same time, the max computer size is listed as 12.8"x8.94"x.76". The S model, which supposedly supports all 13 inchers, has a max computer size of 12.78"x8.94"x.95". The white MBPs are thicker than that. I guess it means that these skins can stretch to accomodate thicker computers, hence my question: will having more room inside the skin provide more protection, as the foam is not stretched? Any ideas?
