Dell No 1 done last night. This is an old machine but again with 2GB RAM. This had been running the RC version so I was confident it would be ok. Went really well; it found the graphics and screen drivers without intervention. The main thing that takes the time is reinstalling software and allowing Microsoft Update to pull everything in. As it is a home PC I have put Avast! Home on it (NIS 3-pack is on the other three). Loaded fine.

One neat trick is that if you have a networked printer, W7 picks it up perfectly - no need to install a driver manually on each machine.

Next job will be to get PHP and MySQL on the Sony laptop. Then I can be happy to move my main work PC...
