If either the 5d2 user or the 180 owner notice it in normal photographic work I would think they would be unhappy, and in either case their issue would be addresse by the manufacturer.
I used the 5d2 because of its ubiquity and because it's well documented that I like canon and therefore I'm not just dumping on a brand. My point was that EVERY modern high res photographic device (Phase, Mamiya, Leaf, Hassy, Sinar, Canon, Nikon, Sony) can show this issue if pushed far enough. If an IQ180 owner is seeing it in normal photographic use then it's not in spec and requires attention. It's hard to tell without raw files (hard to tell what settings were used and how much the file has been adjusted).
In fact, while we are on it, every film also showed tangentially related issues if you manipulated the end result hard enough. For example extremely minor uneven development would lead to slight variations of exposure which would manifest in a streaky manner - but only if you were scanning and pushing the curves around heavily.
@cunim: Every time a customer starts a support case the raw files for the case are place on a server for Phase One to access. Especially interesting cases (e.g. Out of norm performance) one of the engineers from the relevant departments is consulted; often the head of that division. In this way field results are constantly fed back to the designers/engineers. There has been great improvement in the software and firmware in areas that stretch the abilities of the sensor because of just Hthat process. Take for instance the 35xl; at launch the lens was utterly unusable, but with the new LCC routine and improved firmware it is being comfortably used by many customers (with the understanding it simply will never work with large movements).
So bottom line again: if you're seeing it in images in your normal workflow from supported lenses then your back is likely out of spec. If you're only seeing it when you adjust the file solely for the purpose of looking for it then you'd find issues with any camera. If you're at all unsure you can consult with your dealer: that's what they are there for!
