Yay for the chair. Personally, I can't do leather, because I have a tendency to sit at computers for stupidly large amounts of time, and that leads to moisture build-up with leather, and that leads to
discomfort. But if it works for you, then that's good. I think one should have a comfortable computer chair if they're spending any amount of time there. Comfortable, and one that forces correct posture.
I have an Aeron and I think it's pretty great. It's solved the "sitting at a computer for hours and hours and then getting up and having a sweaty ass" problem, and it's comfortable to boot. You can see it here:

Anyway... yay for blood glucose testing kits too. I might have to pick one up just to play with and see how I'm doing. :)
