Always Import to the New Software (Score 1)

I have an archive going back to 98 when i got my first computer and I have always moved to the newest technology and imported my mail at that time, so even though I have used Outlook Express, Entourage, Netscape, and now Apple's Mail I keep all my mail in the .mbox format inside Mail, I get rid of my old archives and just backup my current mailbox format. I also started saving all my IM sessions. I use Mac OS X and the new Spotlight search feature is what influenced me to start saving those. Being able to search through loads of emails and IM sessions seems like a nice thing to have and storage is cheap, I don't mind saving many many pages of what is mostly text. It didn't seem like it would even make an impact of any kind. Hundreds of typical chats are only about 1 MB.
