We got into a debate recently at my organization. We were debating giving some of our IT users beefier computers then we do for everyone else. Currently everyone uses the exact same model of desktop and laptop with no variations at all. But some of our IT users are starting to have serious performance issues with their current setups. The one argument was if it is taking an IT person longer to do their job because of the under-powered computer they need something beefier. The other argument was that we should not be showing favoritism to our IT staff because other staff may get upset about exceptions not being made for them as well. Both are valid points. Administration of the devices is not an issue for us with having different makes within the same brand.
