Not remotely related to computing at all, but I’ve just been updating my diaries, and I use Moleskine. I go everywhere with a Moleskine of some description (they’ve recently released some really tiny notebooks, which make it easier to carry your life around with you). Despite having computers, organization tools, and email, there is something decidedly comforting about writing, by hand, into a physical notebook. Of course, you write in pencil so that the contents don’t smudge, and somehow that just feels even better.
