I will do a final back up of my entire computer via SuperDuper! and Time Machine right now. Afterwards, I will not modify anything on my computer so that the back ups are as up-to-date as possible. I will limit my computer use to web-based applications and services only for now. (Same goes for the iPod touch, of course. No more syncing is to be done until after the Apple Store visit.)
Now's the best time to put Google to the test. Haha.
