I ended up pulling the trigger on the MacBook sale at Best Buy yesterday. I understand that's it's a First Gen device and I was planning on waiting until Gen 2/3, but after all the discounts and coupons I got it for $648. I wanted to know how powerful it was compared to other Apple devices. For example, I have an iPhone 6s Plus and 2011 iMac. Is there a chart comparing it to other Apple Products? Thanks!
