I'm being forced into an timed upgrade by corporate and I couldn't be unhappier. If some of the extraneous software needed to work in the environment wasn't Mac/Windows only, I'd request a hi-res Thinkpad and throw Linux on it. Even my ~2010 iMac at home runs Ubuntu.
You might consider running Windows virtualized. About 5 years ago it was still a little janky and slow. These days those problems are mostly non-existent. I run heavy Adobe applications through VirtualBox and can't tell any difference from native speeds, even on my older laptop.
