I’ve not fully decided yet, but I think I’m just going to go with something like this:
It’s anti-shock, black and simple, cheap, etc. It’s spot on, I think.
I’ll put the NC 10 inside the case that it comes with, then into the anti-shock case above and carry it around in a cool satchel type bag that I got from River Island a year or so ago. It doesn’t look like a “laptop” bag at all, which is really good, because I don’t want people knowing what I’ve got in there. And it looks pretty cool and fashionable, so it doesn’t look out of place like some “laptop” bags do.
