My name's Jack and I'm a shameful Apple defector. I now run OS X and Windows 7 in harmony on my MacBook (give peace a chance). The first PC tip I learned was how to put a little piece of scotch tape over the write-protected tab on a floppy disk so you can overwrite it. I hope to share other such handy tips with you here at Digital Citizen (except, you know, relevant to the 21st century).
