The Macbook Air 11 inch is perhaps the best computer if your work involves getting a lot of stuff done while on the move. Personally, we use the machine as our primary computer and we could not recommend it highly enough. As long as you are not doing very heavy video editing or too much of gaming and stuff, the Macbook Air 11 inch pretty much fits every other use case.
Not only is the machine extremely light and portable, but add in the specifications esp the Mac OSX which is a superior OS as compared to half baked Windows 8.1 and you can see why you would prefer it over most other Windows Ultrabook. If you are looking for a fly deal on the Macbook Air, then this is the time to grab one. The computer is available for Rs 55,000 from Flipkart and although this is obviously not the most recently refreshed variant of the Air, but this is still the mid 2013 model and unless .1GHz of extra processing power is not an issue, you should have no qualms picking up this variant.
On the specs front, the Macbook Air 11 inch comes with 128 GB SSD out of the box which makes sure you are up and working in 8 seconds from a state of power off on your Mac. The Macbook AIr is powered by a 4th gen Intel core i5 processor with 4 GB of RAM. Intel HD Graphics 5000 processor with up to 1 GB LPDDR3 SDRAM will help you breeze through your graphics intensive tasks. Though the system comes with OSX Mountain Loin installed, you can upgrade to OSX 10.9 Mavericks for absolute free from the App Store.
