My decision making process:
Looks like you've evaluated them for your own needs pretty thoroughly - nice
Just going to add my two cents to them to show the difference in our needs:
New retina MBP
Pros:
-Retina display
-lighter
Cons:
-Doesn't appear to be upgradeable in the future to bigger/faster HDs, meaning I'd have to spend a lot more day one
-RAM doesn't appear to be upgradeable in the future, meaning I'd have to spend a lot more day one
-No built in ethernet port; I loathe adapters and as I am a network engineer this is important for me.
-HDMI port; seems un-apple like to me, I don't like this.
Both the pros hold true for me too, but for cons:
* Looking at the closeup of the inside of the body, it actually does look like the HD is not soldered directly onto the logic board. This means that, like the air, someday in the near future a third party company will develop and begin to sell a SSD upgrade option - and the price for these will only go down as time goes on.
* RAM soldered on the board was a bummer for me too, but I bit the (small) bullet of an initial upgrade to 16GB, which I think will futureproof me for quite awhile.
* Sorry that the loss of ethernet is a pain for you, but as I myself haven't used my ethernet port in about 3-4 years, it's no problem for me.
* HDMI is something I wasn't expecting, but I'm actually pretty excited about. It will make it ridiculously easy to connect to TVs in the future for presentations, movie watching, etc.
New MBP (non-retina)
Pros:
-Built in ethernet port
-Upgradeable RAM and HD
-All ports down one side, aesthetically I think this looks better
Cons:
-No retina display, why is this not even an option?
-Has optical drive but at least it's free
-As heavy as current laptop
As for the Pros, I've already mentioned why these things don't really matter to me, and I'd disagree on the aesthetics (symmetry FTW!)
As for the Cons, I agree with you wholeheartedly, except for the fact that I don't really need the optical drive.
Two points I would add:
1. I'd be interested to see a 13' MBP with a retina display.
2. I would have preferred to see a two drive option in the 15" MBP like in the iMacs. This would have a good way to use the optical drive space and distinguish it as a pro model. I think Apple have missed the mark with this update.
1. I would be too, and I thought that this would be a deal-breaker for me on this new RMBP. However, after seeing the product, I got over it and ordered.
2. I agree that it would have been nice to have space for another internal drive in theory, but I think it would have compromised their vision.
All in all, I think that the update wasn't as earth-shattering as it could have been (13/15/17 Retina MBPs, 11/13 Retina Airs), but after I've let those expectations go, I'm pretty darn excited about Apple's announcements today.
