sup guys , im thinking about getting a macbook air , and i did some research about the SSD disks ,the main thing that is making me get a macbook air , besides weight and size factor. -Faster start-up as no spin-up is required. - Typically fast random access for reading – as there is no read/write head to move. - NO NOISE - Ability to endure extreme shock, high altitude, vibration and extremes of temperature – again , because there are no moving parts. those are great advantages in my opinion , but my question is: 64gb is nothing , at least for me 64gb is really small size for a hard drive. photos,music,softwares take a lot of space nowadays. Is it possible to change the SSD disk from a macbook air and use a bigger one ? 128gb / 200gb ? When you guys expect rev B macbook airs with bigger ssd disk and faster processors ? thanks.
