I purchased this laptop as a dual-purpose work/home use computer and so far this laptop has performed better than any previous laptop I've owned, to date. While running parallels it will boot Windows 10 in less than 10 seconds, faster than my HP laptop that only runs windows. This being my first MacBook computer, most of my frustrations in setting it up have been with the lack of application parity between the iPad and MacBook models, but realizing the two run different operating systems I guess this is to be expected. This laptop is blazing fast to boot up and I haven't had any issues with the video graphics or CPU showing any signs of sluggish operation while running multiple applications at the same time. Very happy with the fit and finish of the hardware, and it appears to be very well built.
