Me too - it was easy. It took less than an hour and you have the option to save all your files and programs, which I did - several times out of anxiety.
I was going for the virtual XP option but in the end decided to reinstall all my software - particularly as the saved Windows.old took up more than a third of my C Drive at 38GB.

It's all very intuitive - I was reading and reading and in the end thought 'the hell with it - it can't be all that difficult!' - and it wasn't. I've been working on paid work with it today, not bad given that I only installed it last night.

If you can, forget XP and go for re-installing your old software on 7 - you'll be surprised how much you don't need/want any more. The only thing that wasn't compatible (yet) was Virgin's antivirus protection but there is free security provided called Windows Essentials.

Come on in, the water's fine!
