Cnet News give their view:
"If there is one thing that open source has taught us it's that there are "users" and there are "customers". Odds are that all of your customers will be users first, taking your software for a test drive and then deciding if they want to pay for it. It's all about getting people to consume your software.
The video game industry remains one of the last hold-outs in the war against consumption. Instead of encouraging more use, EA royally botched the launch of Spore with a seriously misguided DRM choice.
It's completely understandable that EA would want to limit the number of computers that you could install the game on. Every major software company has some kind of rationale behind their approach."
