The MacBook Air... or MBA...

Sealed tight like an iPod, nothing is (officially) upgradeable. Even the battery is not replaceable. Anything goes wrong, you have to ship it out for repairs.

It doesn't have a network port. - Not really a big deal. However, if you do need it, you'll have to buy the USB-RJ45 converter of Apple (which costs quite a bit for a wire peripheral).

On the looks department, well, looking at it from the pics, it just resembles a very thin Acer Gemstone. Only when I get to see it physically will I change this view, I guess...

The price.... US$1800 is a bit too much. I thought they were going to price it 'competitively' as from the rumors? Oh well...

In the end, I think this laptop is for those who have too much money to burn ala Paris Hilton. Me, not only am I not qualified to be one of those, I also am not impressed with the device (READ: device, not computer).
