Reverb9 writes "When Canon introduced the Digital Rebel, the world's first entry-level Digital SLR camera, many remarked on its similarities to the 10D , its $500 more expensive big brother. In fact, the two cameras share much of the same technology and so Canon implemented a number of software-based limitations to avoid destroying sales of the professional-oriented 10D. Now, a new hack that restores a previously hidden menu along with a few additional tricks has added nearly all of those 10D features to the Rebel, with an arguably superior user interface to boot. Canon has so far said little on the hack but certainly cannot be happy with its potential effect on sales. This is, however, a reality that more corporations are having to confront. In an era where programming labour is relatively cheap and computer connectivity more frequent can artificial, marketing-driven, barriers between technology products, last?"
