I can't remember exactly what your company does, but where I work we are constantly reimaging machines. Whether we're migrating OS or even if they just have a problem. For most users this isn't a problem since they save nearly everything to the network as opposed to the hard drive. Add to that the fact that no one outside of IT has the rights to install ANY program and everything runs pretty smoothly. Where we run into problems is within our department (where you would most definitely fit). However the IT makes up such a small part of the company as a whole, its viewed as a small price to pay for the benefits.
