Congrats on your deal. Do you have a reference for this or is there a way to accurately predict when Apple makes a model obsolete? My 2012 rMBP is already on its second battery, which is already 2.5 years old and has 512 cycles. The "Battery Health" app I downloaded from app store claims the battery has 77-79% battery health. I'm hoping this laptop will last another year of full-time use (with reasonable battery life) and then a few more years as a device to keep around the house for occasional use. I'm thinking my laptop will *probably* be OK on the current battery, but if I could get one for free, that might be worth being without my laptop for a few days.
