I wonder how many people out there want a ton of megapixels (30+) and don't even realize that most computers would lag like a mother ****** when processing these files... Especially if you are zoomed in to 100% crop and trying to make edits... Post processing 21-22mp images from my 5D's are somewhat slow going on my 15in Corei7 Macbook Pro... And I have 8GB ram and a Crucial M4 SSD! My 27in iMac actually runs slower than my Macbook Pro. The only thing that handles the processing is my PC Rig that I built from scratch. You'll need some serious power if you expect to be post processing in any sort of timely manner. Here's a general idea of my PC setup for snappy processing times on 5D II & III jpegs/RAWs: Intel Core i7 Extreme 6 Core 3.33GHz Processor ($600), NVidia 580GTX Graphics Board ($440), Crucial 16GB RAM, Crucial M4 SSD (6Gb negotiated link speed). This is just the critical hardware. You can go ahead and add on an ATX motherboard of your choice, Cooling system, additional Hard drives, Blu-ray/DVD drives, and any PCI slot peripherals you want. You'll probably end up spending at least $1500 on the tower hardware alone (not including the case or monitor(s) lol) for a decent machine that will be able to keep up with the processing of huge images from your 30+mp camera.
So who still wants 30+mp? You can take the pictures and wait 30 minutes for your consumer level desktop or laptop to catch up to to your workflow. Unless everyone who bought a D800 has a rig that can keep up with the processing resource requirements, I think it might be safe to say that many photographers out there are losing money on time waiting for their computers to render changes of these massive files.
Oh, I'm sorry, but what you just said is a complete lie.
I shoot 5dII and I ALWAYS turn the resolution 3x (up to 60 mpix, 40ish when cropped), and even with my files that have over 50 layers everything works great. Only thing I might wait for is liquify. And I am using a 2009 Mac Pro. And I even played with Phase one files of 80mpix and even then everything worked fine.
Also, consumers consumers consumers. A person who'll buy a d800 is sure not a consumer but a professional, this is not a coolpix.
I just wish for Canon to release a successor to the 5dII aimed at the fashion/landscape/portrait crowd.
