I, also, recommend the Tucano. I've had mine for almost 3 years and it still looks as it did when I bought it.
It has an internal flap to ensure the computer does not rub against the zipper and ensures a snug fit.
The microfiber exterior feels less 'slippery' than a neoprene case and I can actually remove the computer from my briefcase without pulling out the entire case with it, if I so choose.
