I’ve recently had an enquiry about something on Windows Vista. A day or two later I realised I do have a machine with a Vista partition, so I booted into it to investigate.
First impression: my god, this takes forever to boot, and then to do anything! I guess that’s why ‘they’ say the Atom processor is underpowered. Firing up MSIE to go and download the things I was to investigate also took a very long time.
Second impression: wow, this takes me back! On Ubuntu a year ago I had to download a graphics driver capable of driving the Sun monitor. This time it was only the smaller monitor that every modern driver should be fine with, but I got a different problem. Vista’s driver was fine with the 1280×1024 screen size, but the whole screen image was offset from the physical screen, leaving a black band bottom+right of the monitor, and the top left of the display off the screen. That’s something I haven’t seen on a desktop OS for many years!
Anyway, I was able to answer the enquiry. Enough Windows for one year, I think.
 The nearest I can think of in recent years is when connecting an OHP to the laptop for a conference talk. I had serious problems with that as recently as 2005, and moderate problems comparable to the above still happen from time to time.
