Would you expect the Chevy dealer to tell you that the new model Ford would be a better fit for your family's needs? Is your local retailer going to tell you that Amazon has a much better price?
Would you expect your project-based, hourly IT provider to recommend that you move to a solution that would require less time to manage and no project to setup? The answer is no, and in just the past week I've seen this in practice twice!
The reality is that the vast majority of IT providers are (still) based solely on billing time, selling hardware, and making recommendations that generate projects.
