I just bought the new 13" MacBook Air from Staples (MD760LL/A). On bootup, it takes 30 seconds from the time I press the power button to reach the Apple logo. Login appears almost instantly after the logo appears and I'm on my desktop ready to go within seconds after logging in. I'm just wondering if the 30 seconds of grey screen is normal? The time it takes to boot doesn't really bother me - it's the not knowing whether a problem exists or not that's the real issue. Thanks!
