We support both Laptops and Tablets with In House applications. Our Field Auditors use laptops and our Safety Inspectors use tablets. We got military grade tablets for the Safety folks thinking about the "unfriendly" environment they would be operating in, including docking stations with full size KB, etc. for home use.

All in all, the laptop as been the preferred option, even by our Safety folks, who have found they do not carry their tablets with them in the field. Too hard to use, particularly because of the glare on the screen and their unwieldliness. As your client is an accountant, I think he would be happier with a laptop of somekind, even though a tablet has a higher gee whiz factor.
