Same model/configuration I have. I enthusiastically agree with this glowing review.
I haven’t felt so thrilled by a new piece of hardware since I bought our first iPad, and the same feeling of experiencing a new class of device is present here too. If you’re tempted by the 11-inch model’s portability but are worried about whether you could get your work done, put your concerns aside – it’s an excellent machine and more than up to the job.
Having owned one for more than a week now, using it every day (including for development work in Xcode) and travelling for most of that time, I can recommend it without hesitation.
