The "extra cost", compared to a Windows laptop I pay because I like to feel the 7 Mac OSX operating system compared to Windows as a more balanced and less care!
THE DEVICE:
The processing of the device is good! The slim design is already a visual highlight ;-) The speed when booting the operating system is due to fast SSD hard drive is almost always less than 10 sec. Particularly brilliant are the new fan of MacBooks! These qualities are most of the time completely silent and turn only slowly in labor-intensive tasks. This not only improves my "workflow" but also saves energy (term in office tasks 8-10 hours).
When working with "Adobe Premiere" and "After Effects" the Office maturities are of course not to create. But what has surprised me still is that the fan itself when cutting films are completely silent and not even be noticeable at edges of the clip. Only in the 3D area (when switches on the 2 GB graphics card) is "the roar" of the fan then clearly heard (hurray !!! It lives ;-)
CONCLUSION and RECOMMENDATION:
The special thing about this device is that it provides a very high work comfort with maximum mobility! This comfort of hours of working without constantly looking for an outlet to be combined with the quality of an excellent processed laptops with bonus features such as the Retina display and OSX Mavericks have won me over.
I believe also that this device is not's for gamers who due to the continuous stress looking at complex 3D games especially a device with extreme cooling and not with extreme BATTERY LIFE ;-)
