The last line in the above really speaks to what many MSPs fail to understand. In an SMB, adding a extremely complex solution such as an IPOD is not a great solution for the business (or the MSP).
As the saying goes "Fool me once, shame on you, fool my twice shame on me."
If an SMB purchases something that is so extremely complicated, and fragile and then the business wants to dump the MSP, they have to find another MSP (or Meta-MSP @Minion-Queen) to pick up the knowledge and maintain or fix the existing system.
Because the local on-staff IT likely doesn't have the time / ability to learn how to maintain the solution.
