I suspect that 2013 brings the Apple Thunderbolt Retina Display 4k, with excellent color gamut and uniformity (that may well be what's holding up the Mac Pro).
You are to optimistic - definitely not 2013 year.
While the resolution will be unusable for games, those of us who use our Macs in the creative professions will love the extraordinary resolution and screen real estate.
Hah it is also unusable to watch websites like Facebook comfortably.
This is clearly a niche machine, aimed straight at photographers and video editors.
Do you mean amateurs?
The HP EliteBooks and other top-end mobile workstations with IPS displays all use real mobile chips, so they'll be exactly the same speed.
You are right. EliteBooks are solid like a rock - certainly stronger than rMBP. The only one problem with EliteBooks - "Sandy Bridge" generation was noisy, but is seems that HP redesigned it.
No EliteBook has Thunderbolt, so there's no way to attach a RAID at full speed - they are fine in the field with portable USB 3.0 drives, but they don't have a connector fast enough for the big stuff in the studio. while others will disagree with me,
I agree, but remember that Apple Thunderbolt is causing audio drop frames and slowing/freezing of USB interface (some internal devices like touchpad and camera use an USB in Macs). This is significant problem for real pro customers. I can not believe a situation that you loose syncro during video editing or you convert material skipping some important video frames or audio track.
I understand that Thunderbolt is for demanding customers, but we still have a few devices on the market and it is very very expensive.
I'm happy with the GPU (at least from reading the reviews - we'll see when it arrives). It's fast enough for anything except gaming, and this isn't a machine made for gaming. A better GPU would have meant a much heavier machine (cooling), with a heavier adapter and shorter battery life (power). The EliteBooks and Dell Precisions do offer better gpus, but they pay dearly in weight and battery life. My present feeling is that Apple made the right trade there.
I wonder if you'll claim the same in two years when Apple will release a statement like this:

As a customer it is hard for me to forget "bump gate" with faulty G84 chips.
HP stays still with AMD (previously ATi) and it was a right decision in my opinion. AMD have large experience with semiconductor manufacturing (NVidia was always fabless) and it seems that AMD has better offer for notebooks where TDP is more important than result in game benchmarks (except NVidia GeForce GT 640M LE):
28nm GPU chips:
NVidia GeForce GT 640M LE - TDP 20 Watts
NVidia GeForce GT 640M - TDP 32 Watts
NVidia GeForce GT 650M - TDP 45 Watts
NVidia GeForce GTX 660M - TDP 50 Watts
NVidia GeForce GTX 670M - TDP 75 Watts
NVidia GeForce GTX 675M - TDP 100 Watts
NVidia GeForce GTX 680M - TDP 100 Watts
AMD Radeon HD 7730M - TDP 25~28 Watts
AMD Radeon HD 7750M - TDP 28 Watts
AMD Radeon HD 7770M - TDP 32 Watts
AMD Radeon HD 7850M - TDP 40 Watts
AMD Radeon HD 7870M - TDP 40~45 Watts
AMD Radeon HD 7970M - TDP 75 Watts
The Ethernet and optical drive? I have an Ethernet adapter on order with the machine, and for under $30, I couldn't care less.
You spend above 2000$ and you do not have an Ethernet adapter included in price that probably cost in production few bucks

Sorry, I love Macs either but I have not lost a presence of mind.
Ethernet is still used and very useful in some cases.
If it took up the only Thunderbolt port, I'd care, but the second thunderbolt lets me attach something else at the same time.
Tell what is the total cost of all TB adapters?
Apple Thunderbolt to Gigabit Ethernet Adapter - 29$
Mini DisplayPort to VGA Adapter - 29$
Mini DisplayPort to DVI Adapter - 29$
and
Apple Thunderbolt Cable - 49$
You can always to argue that it is JUST 29$ for one adapter
I'll hang a USB 3.0 bluray burner off a hub on my desk if I feel any need for one of those. By going SSD and eliminating the optical drive, Apple eliminated all of the moving parts except for fans and the keyboard, thereby eliminating the major sources of failure - this should be one sturdy computer.
I fully agree! SuperDrive has so poor quality that there is no need to keep it.
What would I have done differently? In an ideal world, this Mac would have had four RAM slots... I'm not sure that I'd have preferred Apple's standard two slots over the reasonably priced upgrade to 16GB soldered - nobody's even seen a DESKTOP 16 GB DIMM yet at any price (the few that exist are slow, registered server modules), let alone a SODIMM - it'll be a few years before two slots in a notebook yields anything over 16 GB (and Apple's 16 GB is fast RAM, almost reasonably priced and increases reliability by not having contacts).
Completely agree. rMBP is quite powerful machine, but only with 16GB and 512GB SSD. Many customers claim that 8GB is not so much for OS X Lion (ML is almost the same)
You also forgot about warranty - 1 year warranty is like spitting in customer's face. If this equipment is so reliable and for PRO customers, why Apple does not offer it with a 3 year or 5 year warranty "door-to'door" and NBD?
