This Was More Fun When Santa Did All the Work: So, let's take a moment to talk about shopping, shall we? Because if you're like me these days, you're pretending to do work while really you're frantically doing Web searches looking for That Thing You Want for Christmas. Or maybe that someone else wants, if you're generous, but this week, it's all about me. My elusive prey at the moment is some sort of bag that's big enough to stow a 13" MacBook but not so big that I can't use it as a purse when I'm going somewhere without the computer. Trying to eliminate the many-different-bags-and-which-one-did-I-leave-my-keys-in dilemma, if you know what I mean. Right now I have a perfectly decent large laptop tote, and a small just-the-basics bag, and a medium-sized backpack, and all of them work just fine, so I don't really have a reason to get a new bag unless it is Just the Right One that replaces all of the above. But it's either hiding from me or costing more than $100, which might as well be the same thing. Where would you look?
