I assumed the whole point of the offer was that they'd be able to run both computers. The old works-with-our-"enterprise"-software computer is kept alongside the new web-browsing computer.
Thats not really how enterprise computing policies work :) If its not centrally administrated, its probably not allowed. At least in the type of environment where people are still on IE7.
I think you missed a hyphen. I was referring to the horrible limited software that many companies use that always seems to have "enterprise" in the name.
If you're stuck in the sort of toxic environment where a new free machine is not allowed because "policy" then nothing can help you.
