I believe there were some problem with HSS with wireless, aint sure though.
Hopefully this has solved all the problems that.

No problem, hopefully things will go well Lynton.
The readme is easy to read and follow so it would go al right.

head really depends on what you want to do with it and of course personal choice.

Personally I don't think a geared head is good for the types of photography you mentioned.
Geared heads are precise and take time to set up correctly, for product photography and landscapes they are good but not for wildlife.

for wildlife I would go for a 3 way head and for portrait I would go for a ballhead if I would use a tripod.

A 3 way head is great for wildlife because if you setup the tripod level you can track the bird perfectly while the camera remains level all the time, ballhead you can swing to all sides so it's not perfect for that but it's more creative and good for portrait.

I've both a ballhead and 3 way head so I say this out of my own experience.

Well here is the official update, there is a readme.txt file inside that explains perfectly how and what.

Difference between windows or mac is simply the file it's pack in.
win = .exe file
mac = .zip file
What's inside is the same so take your pick, I find zip easier personally.

I don't have it so do you notice any noticeable differences?
By reading it they might have solved the wireless problem there was if the flash was the master flash, but I might read that wrong.

Guys get your terminology right.
How can a Single Lens Reflex (SLR) be a reflex without a mirror?
Electronic Viewfinder, Interchangeable Lens (EVIL) is the name of these kind of cameras like the NX10.
BTW is find it a horrid name but well it's what they came up with

I know I might be picky but it's a small effort to get it right.

Something like EVF on a SLR sounds pretty silly if you take it literary.

Depends, nikon, canon, pentax, olympish and all the other true photography brands have of course the knowledge for making a good SLR.
Companies like Samsung, sony, panasonic, etc, are electronic brands and these EVIL cameras are perfect for them since they don't have to deal with complicated mirror systems.

I think the true photographs brands will keep the SLR alive as long as they can since that's their major thing they have over the electronic brands and of course the lenses.
Also these brands need to make a new lens line up if the distance between the sensor and lens change and I don't think many current user would like that.

By the specs they are so good as even wide but the KX is 1 centimetre higher and thicker.

I don't think I would like the grip of the NX10 but hopefully for samsung it might be better then it looks.

Since the sensor is still the same size I don't think the lenses will be much smaller.

Sorry I don't have a photo though.
This the best you can do at the moment, they are roughly the same size but the NX10 is just a tiny bit smaller but it should give you a fair idea.

It's probably just me but I hand hold everything
Camera in my right hand and the flash in my left, it can be cumbersome since the flash and camera are both set to manual mode but it has work for me so far.

And to be honest who thinks the K-M and the K-X are too big?

I don't think many would say yes to that and the K7 seems to be the ideal size for most photographers, some find it on the small side but are quite happy with it so going smaller then that isn't the way probably.
