If you're making Web Mobile Apps (based on PhoneGap, or Titanium if you insist), you have to get a Mac for deploying on an  iPhone/iPad.
Some of us not only don't have a Mac in the house, but also don't plan to ever use one for anything other than deploying apps
(or other necessary Mac usage).
If you're one of those people, this service is for you.
