Smoking is nasty, but smoking next to your computer is ever nastier—there are million little crannies for smoke and tar to get stuck in and discolor. But if you've got a long walk to a window or something (which for smokers means greater-than eight feet, as a rule), you might think about investing in this Thanko USB-powered ashtray, that sucks in smoke and blows out marginally-less smokey air. I've had similar products before and haven't ever had much luck with them, but it's worth a shot, I suppose—at least until someone develops a USB-powered HEPA filter.
