Hello, my MBP 2010 17" still serves me well except that it is a bit heavy to carry it to work almost daily. I don't know when it will be out of order. I was planning to buy a MBP 2016 but I do not like some of the design features. The MBP 2017 probably won't be out until later this year. The announcement of the Surface Pro 5 and Surface Book 2 have also been delayed. Sometimes I feel the need of an extra large screen monitor. As you know, this MBP 2010 17" does not support 4K monitor but if I am going to buy a new monitor, I might not be wise not to buy a 4K one. It would be 30"-43" 4K or two 30"ish monitors. What suggestions do you have?
