I have a 13" aluminum Macbook, and I want to buy a shell and a laptop sleeve for it.

For the shell, I've been looking at Speck products:

And I was wondering what was better-- the hard shell case, or the satin one? Any personal reviews?
Or is there a better place to get shells?

As for the sleeve, I've been looking at Incase ones on the Apple site because I really like that turquoisey-blue colour, but I feel like $40 is a little unreasonable for a sleeve. Any other suggestions?

Thanks!
