Its always a strain, getting a new Mac, and then having to transfer stuff. So why not:
- Install the VMWare beta for Mac
- Convert your existing Windows machine to a VMware partition using Converter
- Copy the VMWare partition to the Mac
- Use Shared Folders to drag stuff across (documents, iTunes, etc).
- Go to the Pub.
Job done? Even if you want to install Parallels and then use coherence to have Windows applications run as separate windows on the Mac, at least this gives you a quick way to get everything across quickly.
Total cost: Zero. (Well, till the Vmware Mac goes out of beta, then a couple of hundred bucks)
Disclaimer: I've not tried this so its only an idea..
