This decision is purely a function of cost, portability, features. And you might have to compromise on something, be prepared. My choice: Asus Ultrabooks. In my case, I couldn't afford a Macbook Air, (I badly wanted a MAC, I couldn't buy with my budget, but just somehow managed to get an ASUS Ultrabook with EMI's) About Asus Ultrabooks-- Compared to MAC's: - They are much much cheaper, ( almost half the price) not compromising on the build quality, comes with Aluminium Chassis. - Has 24GB SSD, Hybrid storage with 750GB HDD( you can configure SSD, and install important apps) - Excellent MAC like Keyboards. - Suggestion: Get an 8GB extra RAM, everything works smooth. - Finally excellent battery life, 4hrs guaranteed with 4cells, if you are looking more get 8cells, but pay extra. Good luck. :)
