A:AnswerI've had my MacBook Pro since 2013. I surely wish I had a touch screen. I don't have an exact comparison but this Dell should give you a good 4-5 years of use. Even now I have a program so I can log onto my MacBook Pro from my iPad so I have touch screen. Technically the MacBook is higher quality parts but for the price of a MacBook Pro i can buy 3 or more of these and always have the latest technology. With Apple going to all USB-C the cost of dongles makes me hesitant to upgrade to the new laptop. Unless you need a MacBook Pro, you won't go wrong with this laptop.
