TiBag
I like my Brenthaven TiBook knapsack, but sometimes it seems like overkill. It's great for travel, but is all that capacity really right when I want to throw the TinderBook in the car and bring it home for the evening?
So, these days I'm trying the TiBag, a messenger-style bag engineered for the TiBook. It's very nicely planned, although I've never carried a messenger bag before and it took some getting used to. (I think the prominent logo might be a bad idea, though; the TiBook is an obvious target for thieves, and advertising that you're carrying a nifty computer in your messenger bag instead of some boring old bearer bonds seems a little ill-advised. Still, they're a tiny company, so I don't begrudge them a little bit of advertising)
