To my incredible surprise, I actually feel that the linux laptop's trackpad works better than the one on the macbook! This was one of the big reasons I wanted to switch back to a macbook and I was extremely disappointed with the results. I was having serious issues even just selecting text with the trackpad on the macbook air.
The author notes a 2-3 second delay in DNS lookups - I'm actually having that problem with my macbook, and not with my linux laptop, and I have no idea what weird Apple goop is causing it or how to fix it.
To each their own I guess. I tried the new macbooks because of what everyone has been saying but was pretty disappointed in the experience, so much so that I was wondering if my macbook air was damaged somehow. The battery life was solid, though.
