So I have both the 11" macbook air and the 13" macbook air and I use them for traveling. Its hard to decide which one to take with me but I love them both. They are fast, small and the screen is terrrific, I love them but I need a horsepower machine also for work so I decided to replace my aging core 2 duo 2.66ghz 15" macbook pro with a new Sandy bridge model. Picked on up from the apple store. 2.3ghz high rez anti glare and love it but one thing. THAT FREAKING SPINNING HARD DRIVE. I can hear it. Its not loud by mechanical hard drive standards but I can hear it. I am so used to the sound of my Macbook Airs (SILENT) that now having a spinning hard drive is driving me nuts. So I am taking it back and just placed an order for the same model at apple online only this time I added the 512gb apple SSD for $990. Great deal by 512gb SSD standards but still a chunk of change. These airs have spoiled me. The thought of using a spinning hard drive ever makes me want to pull my hair out. Well now I just have to wait for it to be shipped. I am sure it will scream, (SILENTLY). LOL.
