"Took 54 mins on my 4 year old SP3. Who cares?"
Took two hours on the laptop I was using this morning. I care, coz I wanted to boot the thing into Linux to get some work done, instead I was left staring into space and twiddling my thumbs.
This is another case where dual booting is preferred to running VMs. It's not my laptop, the people that own it expect it to boot into Windows, the Linux stuff I was doing this morning is rather memory intensive, and there's not that much memory on the laptop. So no room to run a VM.
