Some aspects of the bubble lifestyle irritate me, but this was an interesting read.<p><i>In my home office, I have two large, 30-inch computer monitors -- a Mac and a PC. They share the same mouse and keyboard, so I can type or copy and paste between them. I'll typically do Web stuff on the Mac and e-mail and chat stuff on the PC.</i><p>What does this actually mean? A Mac with a virtualized Windows instance on one of the monitors?<p><i>I do my best stuff midmorning and superlate at night, from 1 to 5 in the morning. Some people don't need sleep. I actually do need sleep. I just sleep all the time. I'll catch naps in the afternoon, or I'll take a 20-minute snooze in the office -- just all the time. Our business is 24 hours. Our guys in Europe come online at midnight. Sometimes, I will go out at night, come home from the bar at 2 or 3 a.m., and then go to work.</i><p>This has to take a toll, right?
