Everything Apple (the Mac heads thread)

Does anyone have any recommendations for a good macbook pro case with some degree of shockproofing? I've got a 15" retina so I feel something decent is in order for when it leaves the house.

I'll be cycling very carefully when it's on my back!

I've got a Thule case for my 15", all good so far... I take it to the office/polo on my bike all the time...
