What would be the best machine for me!? Currently I have a mid 2013 Macbook Air with 2Gz, 8Gb RAM. This is my main development machine, where I use VMWare and Visual Studio 2017 RC (just installed it) on Windows 10. They both run a little slow sometimes, especially if I load up lots of Chrome windows and I start running out of memory. I'm currently testing Visual Studio 2017 RC to see if the performance improvements make any difference. I know I don't need a heavy dedicated graphics processor, so the top of the line 15' Pro is too much. But, is a 15' going to give me a better development experience then the 13'? I don't want to run Bootcamp, I want to keep my environment just like it is with a VM running Win 10 and using VS inside it to develop. In addition to this I currently have a 22' Samsung 1080P hooked up to my Macbook Air and wanted to upgrade to a better 4K monitor, so I would have 2 monitors (1 nice 4K and my 22' Samsung monitor) side by side plus my Macbook screen as a third screen. The 13' shouldn't have any problem with this setup right?
