Main new computer is the 27" retina iMac Have a late 2011 MBP I am putting an SSD into this week. Even that is more than I might need Have a late 2009 MBP with a dying hard drive, a dying battery, a dead DVD drive although I never used that anyhow and have a great working on in my 2011 version as well as a USB super drive for the retina iMac. Was just going to throw it out this week but i have met TONS of resistance from other apple users who seem appalled that i would toss out an MBP from 6 years ago. I have never had a computer for 6 years. This has been the first so I DONT have any issues with throwing it away. IF i were to keep it I would likely only use it on my bed at night time to read through Kindle or web browse and if i fell asleep and it fell on the floor it would not be the end of the world. But it would cost roughly $120 for a new battery and another $120 for a battery unless i just kept it plugged in. Does this not seem a bit much to be putting into a 6 year old MBP? What am I missing? Why such resistance to my throwing it away?
