Security management, maintenance, and recovery for Windows PCs is vastly expensive for enterprises. In most enterprises the cost is easily hundreds of dollars per year per PC and can go well over one thousand dollars per year in many companies. This may sound ridiculous at first, but it is not at all. You have to add up all the IT costs related to security for PCs annually and divide by the number of desktops in an enterprise. The costs are very large. Add up virus scanners, intrusion detection systems, SIEM software, IT personnel's time, and work inefficiency due to security overhead. The big security cost is cleaning up after malware causes harm. IT personnel regularly have to rebuild PCs and clean up viruses. These are the smaller costs. The larger costs are lost work and lost employee time. While these costs can already add up to hundreds of dollars per year, if a security issue results in data theft or corruption or other consequential damage, the cost can rocket into the millions.
iPads are not free for an enterprise to manage, but they are a fraction of the cost of PCs. As iOS gets more enterprise features that allows them to be desktop replacements, enterprises will rapidly accelerate their adoption rate. Lets all hope that iOS 7 paves the way for another wave of iPad adoption in the enterprise.
My company has very successfully moved the entire sales department to iPads. More departments should follow in the future. Admittedly our software developers will still need PCs for the long term, but iPads will be beneficial for more and more job types in years to come.
