Early days with this ultrabook, so my preliminary thoughts are all positive. After checking all the online expert reviews this came out highly recommended, so far I can see why, its a joy to use. As for the reviewer giving 3 star rating who does not own or use it I am amazed Amazon allow that to be posted, especially as after checking a review of the Yoga 2 he rates against it?? its performance was measured to be slower than most in class, so yes it has a bigger SSD but at the cost of slower performance! I will update this review in a week of two of use.
