Currently have 2014 MBair 11 inch, but detest the screen, love form factor, own 4 applet tvs, 2 Mac minis, 2 iPhones, 1 MacBook pro, 1 iPod classic, 1 iPod nano, 1 iPod shuffle, so, yes I am in the ecosystem. But I must run a windows program that absolutely sucks on the MB air with the poor screen resolution. Has anyone knowledge of how parallel's will function on the new MacBook? Will it crawl or be acceptable? Cheers.
