I've now worked out that the Timbuk2 is not for me, as I need something that: - Protects the machine on all sides. - Has at least one other storage compartment or pocket. - Has a shoulder strap so that I can carry it whilst pushing the stroller. - Is not too big and bulky or expensive. I've read the other two threads about 17" bags, now I just want to see if anyone out there has something that meets all these criteria. I've looked at the following sites (but I'd prefer a personal review of the product rather than just reading the limited info on the websites): - Tom Bihn - Timbuk2 - Willow Designs - Waterfield Designs - MacCase - Booq - Sportfolio Also, can anyone tell me if a portrait orientated case (ie pulling it out from the side of the machine) would make it more likely to force the screen to warp slightly with constant gripping from the side? Thanks, Chuck.
