I mis-spoke about the Win 2K SP4 download - it was only 588 K, not M. But it sure felt like M - it took a good hour to download over broadband. I suppose everybody else was downloading Vista or Office or whatever.

Another clarification. For my first attempt at Vista, I booted into Windows 2000 and then inserted the DVD, thus launching the upgrade installer. The second try, I placed the DVD in the tray and restarted the PC. Neither approach has proved successful thus far. Stay tuned.
