My post was supposed to reflect how effective Apple's marketing actually is. The fact is, MBPs aren't obsolete. However, they seem obsolete due to Apple's marketing.
The OP's question was whether the MBP looks dated. And the answer for most people is that it does, even if that's just because of Apple's marketing.
Bingo!
Isn't it amazing that the OP thinks the CMBP are 'thick'. Marketing is amazing when done well. The fact of the matter is, I had the total opposite reaction to the new RMBP. I didn't think they looked all that different. It was hard for me to tell which one was which since none of them are sitting next to each other in the store.
Do you remember when water bottles were a not common? Why doesn't anyone drink tap water anymore? Did our parents get diseases from doing so?
Why the need for drinking water that we have to pay for when water is free from our tap, or allot less expensive than the bottled version. One word :Marketing. (for the record, I do not buy bottled water).
The CMBP's are thin. Very thin. Engineering at it's finest. They are about as thin as you can go without giving up a replaceable HD or SSD and Ram. Any thinner and you simply have to give those up for the design to work well.
Hence the RMBP non-replaceable Ram and SSD. There isn't much more to the design you can do. Remove the OD and make the battery bigger or ad a SSD as standard for boot.
Apple's marketing is such they make you think that just a quarter inch or 6mm more than a RMBP makes it a 'thick' laptop. Like the 2' or 3' inch laptops of years past, are you kidding OP?
These are the facts: Only 6mm or a quarter inch separates the RMBP from the CMBP. That's it. The CMBP can almost qualify for ultrabook status. 24mm to 21mm. The RMBP is 18mm.
I love my RMBP, but the design is not much better other than the screen that the CMBP. Thinner yes, better not by much. To each his own, but that is just my opinion.
