Hello, I'm planning to get a Mac, but I'm unable to choose right model for my needs. My main purpose of getting Mac is to replace existing PC (Sony laptop) and to run Windows apps using Parallels for Mac. I heard that Apple introduced new processors on last month in MacBook Pro line. Is this right time to buy MacBook Pro 15" with the following specification? 256GB SSD, High-end screen resolution etc. Is MacBook Air capable of running Parallels? Any help would be greatly appreciated. Thank you!
