One thing that I wanted to mention though was that I decided to install Parallels for her so that she could continue to use her Windows only software (dictionaries etc).
Parallels includes a tool for converting an existing windows installation into a virtual machine image, basically you install the tool on windows, pick a save location and let it run.
Her Dell had a 40GB drive but the parallels tool converted it into a 12GB (!!) image, which included all three of her partitions, the total conversion time was probably about 6 hours (its hard for me to say as I started it in the morning and then we went out for most of the day). After starting up the image on her MB, it chugged a little as it was installing the tools it needed for the display and device drivers etc which worked very well but it wasnt perfect, there were a couple of drivers that it couldnt identify but I just disabled these. Once done and a restart later and everything was chugging along nicely, so now she has the best of both worlds and is quite happy.
Me personally I was quite impressed at how easy the machine conversion was as in the past even with VMware this has been sometimes problematic. Now all I need to do is find the time to resolve the connection issue between our computers and set up her ipod and we're all done :)
One of the easiest "migrations" Ive ever done.
