Mizzle: It is obvious to me that your experiences of edge softness are related to your use of ultra wide angle lenses on a full frame camera - inevitably angle of incidence plays a major part here and UWA lenses are extremely complicated beasts to cater for these angles of view (up to 180 degrees in a fisheye). Macro lenses on the other hand are engineered specifically for edge to edge sharpness because they are often used for reproducing or enlarging flat plane surfaces and as such have to be corrected for this. Enlarger lenses are another prime example of this principle.
The argument here is not what is in my kit bag, but more that you have stated a flawed opinion regarding the laws of physics in the field of optics.
Dude, you're not getting this at all. ALL quality lenses with an adjustable aperture are capable of delivering pictures that are sharp from edge to edge. However, it depends solely on the aperture, to which I said that it's impossible at f/2.8 or larger - which it indeed is.
Number1 said that "It's not overall sharpness , whatever the sharpness level it should be consistant from corner to corner with a good lens. " Seeing most cameras in mobile phones have an aperture set to f/2.8, I said that it's impossible to do in a mobile phone.
Although I would love to continue chatting, I've got a busy schedule for today, so I'll leave you with photographic proof - the following shots are 100% crops of RAW shots - the left picture is a centre crop, and the right picture is an edge crop from the same picture.
Nikon D700 - 1/2500 sec, 50mm, f/2.8, ISO 100
Nikon D700 - 1/320 sec, 50mm, f/9, ISO 100
Get my point about edge sharpness now? It's totally dependant on the aperture, same goes for the overall sharpness. There's hardly any different in the centre crops, but it's VERY visible in the edges of the pictures. You can't have the same corner sharpness at f/2.8 as at f/11 or so. It's just not possible.
Having said so, I do understand your point about it not being economically possible. It will probably be possible to get sharpness levels similar to f/11 at f/2.8 or larger in a number of years, but it is currently impossible.

I'm going to say this one more time: Nokia's agreement with Carl Zeiss about the so-called Carl Zeiss lenses is nothing but a trademark agreement to say that Nokia's standard lenses have been approved by Carl Zeiss. It has no effect on the outcome whatsoever, and is nothing more than a stupid branding agreement to make customers think that they've got the better optics - and it's obviously working.
pretty much exactly what SE does with their Walkman and Cybershot marketing BS which people fall for.

Yes - and LG, Motorola and Nokia, to mention a few.

Perhaps you're refering to C702? As great as it is as a phone, I find the camera quality quite disappointing
