@Vydorscope: Thats must likely a progressive load of some sort.

Had to laugh as I read your post! The whole commercial / product / interior / advertising photographer explanation is the same the world over, especially when you are away from the big urban centres.
You explain what you do, and then they ask 'do you do weddings as well' ROFL.
My post really was a very gentle poke on that point. I think to have a number of photos, suitably arranged by folder so you can load them in quikpic is fine. That app just has a slickness to it that I don't think any others, and looks good to the users.
I think your untested theory is probably sound enough about CD's & AD's not noticing, or being concerned about the colour being slightly askew. However, part of that may well be down to the experience & competance of said individuals. I have never had a problem with same, but I've read so much on a certain few forums where very many of the most experience and / or leading photogs frequent, indicating their feelings about the declining quality of such individuals. As I say, I'm repeating what others (including those from your part of the world) have said and not from my personal experience.
The other thing I would remark on is that the newer my screens are, the less correction they seem to require in calibration. Hopefully that's true of the panel on these machines!
As a sales pitch, using a tablet should be quick, convenient, and perhaps has a small value in demonstrating that you are design conscious / led, without distracting from the product you're selling. Provides a beautiful snapshot, without the hassle of getting a notebook going!
I think I would definitely be careful about apparent depth of field when screen viewing at this resolution and size. It always seems to me (and I've only shot digital in working environment) that moving from a 15" MBP with Capture One processing a 39Mpixel raw image, to a small screen with a jpeg scaled to fit, you might end up with more apparent dof than you really want. Please forgive me for mentioning that, if you've thought of it already, but with a lot of product, and even some interior, you'll be using movements to precisel y control plane of focus etc. Maybe there are other adjustments to be made as well. There's so much we take for granted in our workflow tools!
