Dongles are the spawn of Satan.
Anyone trying to create another dongle should not be encouraged(preferably shot)..

In my experience: Dongles only affect those who actually purchase the product ,not those who download and apply a crack.And all the main compilers have cracks available if you search hard enough.

I have 6 packages that have dongles , and its a pain in the arse to have to turn off and connect the correct dongle(or combination).
