If you know anyone who can't help but check their BlackBerry at meals or meetings, you might enjoy reading my WebMD article "When Technology Addiction Takes Over Your Life."
I had fun interviewing folks about where they check their PDAs. Apparently traffic lights, movie theaters and bathrooms are not off limits. I also enjoyed talking to Tim Ferriss, author of The 4-Hour Work Week, which has some solid tips about outsourcing your life. In any case, I try to check email less frequently now, which is definitely a time suck.
