i'm looking for a backpack or messenger bag that really protects my 15" macbookpro from bumps - i am spectacular when it comes to dropping stuff so, doing several hours of research, i came up with these two candidates: http://www.sfbags.com/products/hardcase/hardcase.php nice but very expensive and the lid isn't closing tight enough for my taste, besides, it's a messenger bag, lugging this around for hours will take its toll on my back. then there's this one: http://www.brenthaven.com/macbook-cases/prostyle-slimpack-blkwht seems cool, but not a hardcase and I do wonder if that padding is good enough for clumsy me... mind you, there's tanks like pelicangear but they seem a bit over the top, heavy and more geared towards the battlefield than the city. ....so...feedback is greatly appreciated... experience with those two? other suggestions? thanks.
