I have been intimately involved in a corporate tablet specification, bake off and decision process, so I am not blind to anything that is required to use tablets in a corporate space.
In the bake off it really came down to the ecosystem surrounding the product. Not the apps running themselves. The apps were developed in house or used off the shelf commercial apps modified for their internal purposes.
I personally pitched an OEM Linux based tablet approach based on the fact that the use of Linux was already universal within the company.
No one would say (and I repeat, no one) would say running RHEL in a datacenter cloud is the same as running tablets in the field, but many of the required knowledge and tools sets are similar. The synergy and interest in career portability was very, very high.
I am not at liberty to share all the details of the decision process, nor can I share who won the bake off, all I can say is that all the low level technical requirements were easily met with a Linux based tab. Many of them were very, very specific that the competitors had to jump through hoops to support.
Everyone has to meet their needs in their own ways, I am only throwing out what examples exist. I am sorry that my 5 sentence post over estimates their needs in your mind, as I didn't expect to write a large justification of it, merely make a thought provoking suggestion.
