Kirk McElhearn recently picked up a Mac Pro and he’s been using it for a few days:
The Mac Pro has done exactly what a good computer should: it has made itself unobtrusive. I don’t hear it, and it doesn’t slow me down. It’s a shame one has to spend the kind of money this computer costs to get those features, and I hope that, one day, all computers will be like this.
This is what I feel when I’m using my MacBook Air. It may be a couple of years old now, and not nearly as zippy as the Mac Pro, but it doesn’t slow me down. I often forget I’m using it because it’s so unobtrusive and quiet. It’s sublime.
