The totally irrational hate this MBP has received is really funny to me. It turns out nerds are super conservative. Change anything and they act like it's the end of the world.
And God forbid you should say you actually like the change and then you get people popping up telling you that you're wrong, you can't trust your own preferences, and you actually don't like it.
It's a slightly modified laptop with a few changes that most people don't care about or prefer. Get over it.
People are showing all the traits related to resistance to change. Seeing this whole thing through the ADKAR model, Apple misses the Awareness and Desire part by "surprising" current customers on the release happenings.
There seems to be an inherent problem with this way of rolling out changes that conflicts with taking care of existing customers. Perhaps treating current and potential customers differently would be an idea.
It is clear that other people don't like it. I hope they are able to find machines that works better for them. I posted my original comment just to give a counterpoint from the perspective of somebody thrilled with the purchase.
