First of all, MacBook Pro is not a specialised niche workstation machine, its an
all-purpose mobile workstation. The MBP is a true jack of all trades - for every particular task, there is a laptop that would do that task better - but the MBP is about packing a lot of power and decent quality into a compact, mobile form. If the OP is looking for a specialised photo/video editing workstation, there are Precisions and Elitebooks for that.
Now a few additional remarks:
- the rMBP display is 'good enough' on the go. For serious work, most photographers would probably use an external display anyway.
- the temps do not matter as long as the computer is performing as expected. I am regularly running long-lasting simulations on my rMBP which push all 8 virtual cores to 100%. Never had any problems with overheating. Same goes for gaming. Speaking of 'burning fingers' is just silly. It gets warm, thats it. Nothing wrong with that.
- there is no point of putting a 10bit panel in a MBP because OS X does not support 10bit color output in the first place. So yes, already this makes it less suitable for professional photo editing work (but see the P.P.S.)
- I wonder why the mythos of 'macs being for photographers' still persist. Photoshop is clearly more stable and performs better on Windows these days. The only thing OS X offers over Windows is convenience - but if all you do is edit photos, then you don't need it.
P.S. Equating the narrow niche of photo/video editing to any type of professional occupation is silly in the best case and quite insulting in the worst. I am a 'professional' scientist. I use Macs because they are the best computers for my job I have tried so far. And I have work with most of the OS flavours which exist out there. Now, if the OP would have argued for 'MBP being less optimal for professional photo/video editing then a specialised workstation', I would have to agree.
P.P.S. Here is an interesting
thread discussing the sate of 10bit color on major OSes. I am a total noob, so I have no idea, but people who write there seem to know what they are talking about. A very interesting read, IMO.
