Same story at my previous job. Actually, my work laptop had been faster than my personal one for a while because I had gotten a special purchase due to the nature of my work and IT didn't know what to do with it (we contracted IT services out to a 3rd party. We were a small non-tech company). But then someone caught wind and I was made to figure out how to get IT's tracking software installed for them. And that's when I started working from home all the time (a situation I could manage as the non-tech company wanted me to own the code personally. Yes, a little weird, but it was all a tiny sure other for the company).
It's not the tech, it's the bureaucracy.
