Back in the 90s, many of the engineers and geologists in the mining company that I worked for hated mainframes and loved pcs. We had good word processing and spreadsheets on the mainframe so this wasnt rational thought in the view of the IT department that I worked for. Nevertheless, we eventually gave in and let them have their PCs and the users went from hating us to loving us. They also started to mention that they like the mainframe (it was actually a Vax Mini computer or 2) a lot more than they used to. I suspect this phenomenon is just starting to occur between Tablets and PCs.
This article from september last year discusses this topic and as us PC developers are now the new IT department to tablet users, we need to get a handle on what is happening with our tablet users. Eventually when tablet users have had their fun, we can pull them back to less fragmented solutions.
