Getting a new machine is really fun sometimes, but it can also be a royal pain in the butt. I despise the "burn-in" period (as I call it). This is the period where you need to adjust and tweek and frob every knob and adjustable piece of the machine until you get it just right.
Ironically, however, I find that this burn-in time really only happens with PCs. Particularly desktop machines. Especially expensive PCs. It seems as though the more a machine costs me, the more I have to frob with it. :/ Why is this? :) There's got to be some law of nature which makes it this way. :) Whatever the cause, there's nothing like the day when you can finally declare yourself done with all of the frobbing.
This of course, all begs the question: Why didn't I need to frob with my Mac?
