Apple Macbook Air - Targetting a new market segment

Apple’s new ultrathin laptop (new apple Macbook Air) does not seem to be a regular product from Apple. It is lacking many features users look for in a laptop. Apple, generally, try to launch products that give something more than the expectations of the customers. After analysis the features of the Air, it is apparent that Apple is trying to target a complete market segment with this product. Company is expecting that user of this new laptop will already have another laptop or PC at home and office so this laptop will be only for the people who needs to carry a laptop with them everywhere. But this product is not even for the customers who travel too far and for too many hours. This is for the business clients who have to travel and give presentation in same city or state. Apple has not given removable battery so it cannot be replaced and users need to depend on the life of the battery only (that is less than 5 hours).
Apple is trying to market this product to the user who don’t like working on the PDA and like to see little big screen but don’t like to carry heavy laptops either. I am not expecting too high sales (in term of the numbers) of this laptop. Of course Mac users should not make mistake of buying this new laptop if they need full fledge product otherwise they will be disappointed. Apple should also communicate this through advertising that they are targeting different market segment otherwise if it goes in the hand wrong customers that will create poor reputation for the Apple brand.
