I've been commuting on my cruiser for maybe 6 years. Only 3 miles each way but like several have said above, use whatever you want. On occasion, I've even commuted on my 7 foot skateboard.

Squid, I really like that tool, that thing is perfect.

If you know where the tire/tube was punctured, I've been known to fix the flat without removing the wheel. It's not as hard as you think.
