Unused overpowered, much-used underpowered kit
Why a field-swap? Really should've swapped that before handing the kit out to them. Really big screen and expensive-branded keyboard (and maybe a keyboard overlay for some really expensive software package, possibly without owning the package at all) with a big and impressive (but mostly empty) case juuust visible under the bigwig's desk, and all the processing power in a dinky older case tucked invisibly away at the secretary's.
The local IT department isn't just there to "provide kit", that's what the supplier does. What the local IT bods should much more concentrate on is making the technology work for the local users. And if that includes not so much working around, but catering for social needs like this, well, I think by and large us techs have been dropping the ball a bit.
Of course, we thought we were hired for our technical skills, not for our nonexistent social skills, but at the rough end, that's far from true. This doesn't mean giving in to every whim, but it does mean matching user needs, including non-technical ones, to what the technology can deliver. And if it's form, not function they want, well, let's give the extra functional power to someone else. Just have to understand what they're really after, what they need, and give'em that.
