Can we all agree that come fall of 2015 you still will not have purchased one, no matter what Apple has done to the design?
It took you about 11 years to buy your new iMac - and even then you went back and forth, struggled over specs, second-guessed yourself, agonized, regretted, re-thought it, etc. - so...
Hell, if you have a Mac notebook - of
any kind (including a model that hasn't even been created/unveiled yet) - before 2016 -
no, 2017! - I'll write a check for $100 to your favorite charity (depending on my cash flow at the time, I may generously increase that amount).
My $100 is safe. Haha.
