My sugesstion is you get
Tumi. It is more expensive, but the quality is fantastic. I'm particularly fond of the "flap" bags, i.e. something that looks like
this.
You don't have to get that one of course, they have a number of flap bags. But you'll find that with the flap, the computer is well-protected yet you can expand the bag to fit some stuff if you need to.
Also, Tumi has lots of good little things. The cushioning is great, all the pockets and stuff are sewn really well and can take a lot of abuse. Also, my Tumi bag has this tight keyring holder/thingy in one of the zip pockets -- it's a great place to latch your keys when you're on a plane, because you know the keys aren't going anywhere, period.
Anyway, all my luggage is Tumi. At a minimum, I'd go to a Tumi store near you and get a feel for their stuff. I've had my current Tumi computer bag for like six years now, and I'm hard-pressed to find even a thread out of place. I put in a Macbook Pro, Nokia phone, Bloomberg reader card, and all the regular stuff.
If the Tumi store has a limited selection (as they sometimes do), order online.
