What reviewers say

Reviewers praise the portability, display and Force Touch trackpad, finding it responsive for everyday work but less suited to demanding tasks. Both question the price and restricted connections. Macworld finds the shallow keyboard takes practice; MobileTechReview adapts quickly, but finds mixed-use battery endurance below Apple's claim.
