Things to do, things to do! This is what I recommend doing, as this is what I will be doing.
Make backups of your data from 2002. I mean, backups are a good idea, but since it’s a whole new year, it’s the perfect time. I plan on making backups of my digital photos and email from 2002. With Mac OS X, Mail.app, and iPhoto this is pretty easy, it’s mainly just a matter of copying the right directories to the right place, and then burning them to CD-ROM‘s. Of course you’ll want to remember to make two copies of each disc, and store one set of copies offsite. As for what ‘offsite’ means to you, you’ll have to decide that on your own.
