I'm an IT Consultant
My job is to supply PC's, Laptops and Servers ( amongst other geeky things ) day in and day out...
I have a 13.3" Macbook in the Aluminium Unibody
I would not buy anything else, I still have the same Macbook that I bought back when it came out in 2008. ( This was before they became Macbook Pro with the light up keyboards )
It has been around the world twice with me, been kicked, dropped, abused.
In the years that I have had it, I have upgrade the RAM to 4GB, I had replaced the battery once 7 months ago because it was only lasting 2hrs and recently I changed the hard disk to a solid state just well cos..
Oh and the DVD Drive died but that was my fault for traveling with a DVD I had forgotten about in it.. ( FYI dont do that it breaks drives )
It is still as fast and solid as the day I bought it .. I cannot say that about any laptop I have owned before.. Or that I could supply now to any of you.
In the time I have owned it, I have only needed to reinstall the OS twice and once was because of the new SSD hard drive.
They are truly amazing and worth the money.
I would personally avoid the new 13.3" Retina books because they are just too thin and far to fragile.. but the rest of the range.. Worth their huge cost.
