Hi all, After buying the macbook air (13 inch) at the apple store, I am directed to one of those tables for a test run. Is there a list of things to look out for before taking it home? (esp. what does a trackpad sound like when you hard press on it) - Previously i bought a macbook pro 15 inch and within A DAY, the trackpad made an odd clicking noise when i tapped it lightly. - Also, it got very hot easily (burns my hand). - It makes a weird noise when i boot it up from switch off/hibernation. like gears turning. Thx.
