Ok, so my friend has a 2009 Macbook Pro 2.26 core 2 duo with 250GB 4gb ram. It is so slow and she will be purchasing a new 15" macbook pro retina (base). I currently have a 15" retina 2.8GHz I7 quadcore with 1tb SSD (top of the end of late 2014 model). The problem is that this laptop was well over $3,000 after taxes. I just have this laptop hooked up to my monitor and use it as a desktop. I currently just use my macbook pro for gaming. My friend will sell her laptop for $200 (or maybe $150). I told her that she can reinstall everything to see if it goes faster but she wants a new laptop. I go to college and I am always very paranoid with my macbook pro so I would love to have a beater laptop to bring to school and just do school work on (but that defeats my macbook pro retina's use!). Should I just buy hers and reinstall everything and replace the battery and use that and sell my 15" and buy a imac for cheaper and have a bit better specs? What will be a good idea?
