Not even remotely sad. I'm actually very happy my upgrade timed perfectly with the release of the Mid 2012 models. Also, they're no older than the 15" retina given that both were released at the same time and with the same Intel processors and chipsets as well as the same NVIDIA GeForce GT 650M (and/or Intel HD 4000) GPUs. The only thing "old" is the body design, which really, is far better than the retina design. The qualification exams that ACMTs have to take to become qualified to service the retina MacBook Pros only further illustrate just how needlessly ridiculous some of the design changes were under the hood. So, no, I'm not a "sad old mbp owner", I'm a "happy current gen non-retina mbp owner".
all my apps are updated besides "caffeine" and they look AWESOME. i also love the highter screen resolution, more space to work with and yes the thinner size does matter.
i have both and i would never go back to a "regular" mbp
I have no trouble lifting five pounds, my 1680x1050 resolution is plenty and it gives me the same real estate that my 20" Early 2006 iMac did, and I'm clinging to apps that will never be updated (like Final Cut Studio 3, QuickTime Pro 7, WarCraft III, Disk Inventory X, among others) as well as apps that will likely see a very slow transition to retina if ever (StarCraft II, Steam, games that are not Civ 5 and Diablo III, Adobe CS5 apps, etc.). So, no thanks. Glad you're happy with it though. The more people that are happy with retina, the more developers and content creators (as well as other computer manufacturers) will speed along this transition to retina displays so it becomes standard and not a novelty, because that's obviously where display technology (and software supporting it) is to be headed.
13" doesn't have glued battery.
I also have both my old classic and retina at the moment, 15"... So happy I got the retina.
Two of the battery cells are removable. The rest of them are not. The ones that are not, are glued. The removable battery cells are not listed as order-able parts in GSX and they are not intended to be removed or replaced.
First of all, when you configure a 13" cMBP with 8GB of RAM and a 128GB SSD, it comes out to $1,499. That is just $200 less than the $1,699 price tag of the rMBP (to all of those do-it-yourself RAM and SSD upgraders: know that the masses have little interest in tearing open their $1,000+ machine to add aftermarket parts).
Good for the masses; sometimes people don't have money to pre-upgrade their computer and they'd rather not have to spend so much money on upgrades. Opening up a $1000+ machine so that you can spend $60 instead of $200 doesn't sound to me like a bad thing. Or do you feel that I'm wrong in that?
Also, bear in mind that as far as cMBP vs. rMBP debates go, the 15" rMBP when configured identically to a 15" cMBP is $200 cheaper. The fact that the opposite is the case with the 13" model is stupid. You cannot refute that.
So for an extra $200 (when you compare apples to apples), you get 4x the resolution in a thinner, lighter, and more modern design. That was worth it to me for sure. After staring at the retina display, go look at the cMBP and be prepared to cringe at that non-IPS pixelated screen. It's like holding and iPhone 3G up against an iPhone 4 or 5.
Would you like some water with that Kool-Aid?
By purchasing the base 13" cMBP now, you are essentially buying a computer that came out in October 2008 sans a better Intel chip. Go retina and be happy.
That is the most ignorant thing I've heard anyone on these forums say in a long time, and mind you, you have some stiff competition in that arena!
Let's see what's different about the Mid 2012 (non-retina, unibody) 15" MacBook Pro from the Late 2008 (non-retina, unibody) 15" MacBook Pro:
-USB 3.0
-Thunderbolt
-Built-in battery with 7-hours of battery-life (versus the 3-4 of the Late 2008 and earlier batteries)
-QUAD-CORE PROCESSORS
-60% faster RAM
-WAY faster graphics
-SATA III/6.0Gbps
-2012 Intel Chipset technology (compared to the GeForce 9400M's functionality as a system chipset), though maybe that's cheating given that I've labelled off a ton of its benefits already
Now, let's see what's different between the (Mid 2012) MacBook Pro versus the (15" Mid 2012/13" Late 2012) retina MacBook Pro:
-mSATA connector instead of SATA connector (still the same version of SATA otherwise)
-One additional Thunderbolt port
-HDMI
-Soldered on RAM (same RAM type and speed)
-glued on battery (offering the same operational battery life of 7 hours)
-Retina display (about the only groundbreaking new feature setting the two models apart)
-MagSafe 2 (same wattage)
-Removal of ports (which really doesn't speak to technological advancement as it does to needless minimalism)
The differences cited in the first list are far more drastic than the differences cited in the second list unless you're only paying attention to the superficial details, but you wouldn't be so superficial as to do that now, would you?
Choose 13" rMBP over 13" cMBP, I would. But much better investment I think, 15" rMBP is. Yes, hmmm.
If we're talking about good investments, then a computer you can't upgrade is a worse investment than one that you can, especially if their technical specs (display quality aside) are identical. But if you're talking bang for buck, then the cMBP wins in the 13" arena and the rMBP wins in the 15" arena, assuming you're only considering models with Apple-supplied SSDs in them.
I agree with the statement above, especially those last three things (Yebubbleman, I guess you and I are the biggest proponents of the cMBP on these forums

). I was in the exact same situation, and decided to go with the 13'' cMBP/uMBP over the 13'' rMBP. Reason being is that I love the user upgradeability, and for most cases, if something breaks, you can fix it yourself. I'm sure the Retina is a wonderful machine but there is definitely something to be said about the ability to change things.

Hope you enjoy your choice!
Heh...yeah, we do seem to be a fan of practicality. A feature that appears to be lost on the majority of Mac users these days. Oh well. Soon the non-retina unibody MacBook Pros will be gone and this new design will be the only option. I'll eventually be comfortable with it. But I'm not now and I don't think I will be until I'm naturally ready to replace my Mid 2012 non-retina 15" MacBook Pro in five years.
