Actually, they guarantee additional revenues by doing things like sealing batteries in your phone. You're then forced to send it to them (I guess you get a refurbished unit or, for any of you Apple owners maybe you can clarify, you have to wait to get your old phone back). I really think if Apple wants to keep grow this product and keep reeling in revenue from it 2-5 years out, they're going to have to look to business enterprise needs. That means not doing stupid things like sealing in the battery (businesses aren't as willing to trade in equipment that may contain proprietary or intellectual property), locking you to one carrier and one technology (yes a lot of enterprises use AT&T, but many use other carriers, especially since GSM has a much more limited footprint in this country), offering more business productivity apps not so web-centric ("cloud computing" presents big issues for businesses--they've got a growing body of state laws that restrict the handling/access of client information, as well as restrictions on handling/access of information that may be subject to discovery in future civil litigation and restrictions on handling/access to protect intellectual and propreitary property--they will never be able to allow employees to store data on just anyone's server; IT security policies will limit where their data is stored and who and how it's accessed).
