A new machine - a MacBook Air

I was looking at these since they came out a few days ago.Why upgrade from the old MacBook Pro Late 2008? Is it even an upgrade?Well, the biggest reason is the size and battery life of the new machine. It's a compelling argument to have something as light as this computer that can honestly last more than 6 hours of real use. Even with the CPU cranked it's been estimating around two and a half hours of run time.The MBP was getting around three hours when it was idling.That's a huge difference!The screen, while it's 13", is actually the same resolution as the 15" MBP.So I walked into the Apple store in Legacy Village and picked one up and brought it home.So far it certainly seems like an upgrade from the MBP. I can't complain about the performance of the i7 processor. I do wish it had more memory, but I'm figuring that with the flash storage a bit of swapping isn't going to be completely deadly.Speaking of the flash, I can attest that it's fast. Launching applications has never been faster for me, even on the bit iMac upstairs.So far I'm really happy with it. I'm surprised in a way how fast it is. Likewise I'm very surprised how good the audio sounds.Here are the weights of the Mac laptops I have around:

• Mid 2011 MacBook Air: 2.95 lbs / 1.34 kg
• Late 2008 Unibody MacBook Pro: 5.52 lbs / 2.51 kg
• Mid 2008 MacBook: 4.91 lbs / 2.23 kg
