The big thing is the out-of-the-box experience. So Nokia putting its foot down to not allow tampering this out of the box openness and experience is good for all usres.

It doesnt matter that some peoplenkniw how to flash the device to original state. It matters that NO ONE should have to care to flash their device just to open it up.

Its about time ISP are put down in their place.
Will Nokia have to pay a short term price for such a anti-ISP stance ? I think yes. But in the long run this is good for Nokia and more so this is good for customers.
