The review concludes:

We’re still hard at work on the MacBook Air review, but this data was too important not to share right away. By now you’ve heard that under “normal” usage, the Air can only manage about 2.5 hours of battery life. That’s true and at the same time it isn’t. I touch on part of this in the review, but the MacBook Air isn’t designed to be your work notebook – no ultra portable is. It’s a notebook for a writer, for someone taking notes in class; it’s a second notebook, or a third system. As such, the typical usage model can be very different than your standard notebook.

To be fair, MBA lasted 4.27 hours on browsing the Web or playing MP3 music. I admit, this is good enough for me since I use my MacBook primarily to surf and blog. What I don’t understand is why watching a movie on the Air sucks the battery faster than having the WiFi on. Maybe the testers didn’t turn WiFi off.

It’s .16 inches thin at the slim side and .76 inches on the thick side, aluminium, LED backlit screen, the keyboard “is the best we’ve ever shipped,” as Steve Jobs put it, and it’s got this yummy feature called a “multitouch gesture pad.” Yes, it’s a bit of an iPhone too, because you can rotate, resize and move photos by sliding your fingers over the trackpad, pinching them together or moving them apart – just like on the iPhone screen.

So why are people complaining about MBA? Only one thing really… NON-USER-REPLACEABLE BATTERY? What the hey! Never mind the lower than usual processor speed, it’s an ultraportable after all, and never mind the absence of an optical drive, the lack of ports (only 1 USB here) or even the slower PATA hard disk, but a battery you cannot access without voiding your warranty?

PS: is the non-replaceable battery, the 1.8 inches 4100 RPM PATA hard disk, the lone USB port and the lack of a DVD drive enough to push this Apple product to the drawing board from whence it came?
