Your name takes up a kilobyte of space. With the latest $300 16-gigabyte hard drive in your computer, you have 15,999,999,000 bytes left for Starcraft, Hover, and Myst, not to mention all those e-mails you absolutely must keep, or the 700 bookmarks on your Netscape browser, and the programs for greeting cards and spreadsheets and slide shows that you hardly ever use, even, if you work for this magazine, the 20,000 names and addresses of your subscribers and eight complete back issues, in case you can't remember what you wrote. And it all fits on your desk.
