The major software companies moan about "pirates" copying/using their software without paying for it. There are of course other organisations who charge unfairly for software. The current ex-tax software prices for Adobe software products are a case in point.
If I download Adobe's InDesign CS5 while sitting in USA/Canada the price will be $699 US; however if I perform the same download from the UK the price will be $952 US. This 36% uplift on price is totally unacceptable. It is also bad business practice for Adobe. They'd actually get more business from me if they priced their products fairly.
