I haven't written as much as I want to lately, partly because my office moved.
In terms of actual mechanics, one really has nothing to do with the other. Twenty years ago, even ten, I did sit at a computer at my office and write things. But that hasn't been true for a long time. I write long notes in an iPod and iPad (along with actual, honest-to-god notebooks and legal pads), but I do most actual writing on my little pink netbook, which goes where ever I go. And most of our work lives in The Cloud. (Although I am the only one who believes our words are just roaming around up there, in an actual cloud.)
