Well... I do. (Carry checks.)

I am one of the most "wired", techie-geek people I know... but I still carry a checkbook. I'm rarely home. And I occasionally want to write a check. Heck, I mailed off two while traveling last week, both were donations to small non-profit type organizations. About to send a third to the guy who cuts my grass (that I'm never home to deal with myself).
