If you want a tablet for home, for a bit of browsing then the cheaper Android tablets may appeal but if you are using it for work purposes you are going to want something easier / cheaper to manage (so an iPad may actually have a lower TCO), better built and yes staff do feel better given better tools and the iPad is widely perceived (regardless of individual opinions) to be a 'premium' product. So any extra purchase cost is insignificant.
My guess is they looked at how easy to deploy, develop, manage and maintain and the TCO was significantly lower for iPad plus developing bespoke apps could be a very significant cost and iOS is less of a moving target. Think we will see a lot more tablets in business over the coming year.
