Ive been using this beautiful BEAST for the past 4 months now and my review might seem a bit biased and promotional but please take into account that Ive used Ubuntu over my HP Pavilion 6121TX(a very powerful machine of its time) for four years before switching to MBP, so the comparisons that Ill make here, will mostly be between the two experiences.
As you would have already noticed, the specs(and price) of this laptop are almost unbeatable and an objective analysis of this MCB is as follows:
PROS:
NEVER Hangs: I mean quite literally, it just never goes out of RAM. Add it to the SSD performance, which Ill be addressing in the next point.
SSD: At the time of writing this review, I just copied a little over 5GB of data from one part of my computer to another in less than 10seconds.
Optimized OS and Long battery life of upto 8-10 hours.
Aesthetic Appeal of Apple(I realized how big a deal this was, when I bought this machine, i.e. also my first Apple Product)
Retina Display: My previous screen had a semi-HD resolution so this transition has brought to my notice some never before changes in display.
Touchpad: The force trackpad is out of this world in both performance and features. Detects even the most lithe movements of your fingers.
Wonderful sound quality
And the list goes on.
CONS:
Major setback on your pocket
Costs your around 25K more for two years of additional warranty
No native LAN Port(but really youll love it for its thinness more than youll miss the stupid broad LAN port, I do)
You wont find drivers for printers easily, so better check that whether your printer manufactuer has released their/3rd party drivers for Mac OS X. But thats not specific for this laptop but all MACs.
