As others have already stated - figure out why the tube failed. If you don't do that, you may end up puncturing the new tube because of a piece of wire embedded in the tire, or due to poor / lack of rim tape, improper inflation, etc.

Align your tube valve with the logo / writing on the tire. This may help you locate the source of the failure, should another failure happen. That, and it looks more professional.

I don't use any special flat-resistant tubes on my commuter. I do, however, use puncture-resistant tires.
