I decided to go with the new iStart from Apple. It does everything an iPhone does:
1. Play your favorite Cars tune
2. Call your wife and explain why giving rides to hot girls is a community service.
It uses satellite radio amplification to give it more cold cranking amps than the Microsoft ZuneStart.
