I am wondering if there is anyone out here with Timbuk2 (Classic Messenger or Laptop Messenger or Freestyle) and a MacBook Air. What model (XS or S) works perfect for the Air? I also have the in-case thin sleeve that I use to put the MacBook Air for care while traveling. I have an Air and an iPad. Sometimes I take the Air with me as I commute via subway and sometimes I just take an iPad. I want to know which Timbuk2 to get: Classic (XS or S sizes), Laptop (S size), or FreeStyle (XS size). Thank you all.
