I bought one extra on launch day to keep at my job. I have a 4th gen iPad that included one, so that brings it to 3 official Apple cables. I also ordered 2 knockoffs for $8 from Zagerz.com to have as extras. 5 cables in total. Keep one plugged in for charging at home in the bedroom, one at work, and one plugged into my MacBook Pro for syncing. I have an extra knockoff at work and keep the other in my iPad travel bag. I'm looking to buy a 10 ft Griffin cable once they become available too.
