I'm looking for a nice thin, cool leather bag to carry a 13" MBA and an iPad. Have been plowing the web and reading this thread http://forums.macrumors.com/showthread.php?t=1220990 and have taken a liking towards either the Happy owl briefcase (http://www.happyowlstudio.com/collections/all/products/briefcase-for-macbook-air-13) or Hard graft's Flatpack heritage (http://www.hardgraft.com/products/flatpack-heritage) Are there any owners of these bags who can comment on plus/minus sides? I realize they are quite different beasts but both look to be of good quality and built towards fitting a MBA and iPad and not much else (which is what I am looking for). Any other similar fitting leather bags I should look at? Thanks for your time.
