One good thing about MC is the newer versions have a tool that allows you to collect recipes from the web by highlighting portions of the reciped, click on the title of the portion (title, ingredients, directions, etc) and then just load them into the program.
Hmmm... that would certainly be handy for converting all of the recipes that I have in my personal cookbook (word files). I only have a few hundred recipes, so it wouldn't be too tough. I may have to puchase MC one of these days.
As to PC's, I'm keeping my old Windows 2000 laptop as a permanent emergency machine for old software and programs.
