Having been in IT for 32+ years, I have worked on a variety of hardware. I suppose the slowest computer I used was an IBM 360/25 (total RAM 15K), however the slowest PC to run Visual Studio was at a particular client site. In the morning after logging in, we would start our PCs, lock the keyboard and go to the drinks machine. We would stand there and drink one drink, get another and then go back to our PCs. After giving the three-finger salute (ctrl-alt-delete) and entering out password, visual studio would still be starting!
On the day I left, I was told they were about to upgrade the PC's from 256Mb to 4Gb of RAM - a little bit late! This is an important lesson, Visual Studio does need a lot of RAM to give the best performance.
