Well, that Palm device that finds the nearest Starbucks is awesome and I wish I had one! As a Starbucks addict, I understand the importance of knowing where to get my next fix.
I agree with everyone else about the laziness thing, though. How hard is it to get off your butt and go inside to order coffee?! I mean, is it THAT DIFFICULT?! The ONLY time I could see it being a good idea is if you're, say, just coming from the gym or just woke up and look absolutely terrible and don't want anyone to see you. But even then it's just not worth it. That's what husbands are for, anyway -- "Honey, I can't go out like this. Would you run to Starbucks for me, sweetie?"
