Re: Productivity peaked around Windows 2000 Professional, perhaps XP
no flames, just a recommendation: Boot Linux, run XP in a virtualbox VM.
I think that will work best for ya. Try it, you'll like it!!! Use the same license key, even. And backups of an XP VM should be a BREEZE (export virtual machine - voila!)
then you will not need NTFS partitions and can make it 100% Ext4. If you got a new hard drive, did a fresh install, and tar-copied your /home it would go fast, then maybe turn the old NTFS partition into a virtual drive for VBox [I think you might get away with a copy utility for this part]. EVEN FASTER!
