I agree that dongles are hassle, especially for somebody working out of the office very often. Dongles on laptops tend to break off or get lost, etc.
Anyway, most of those advocating against the new licensing scheme are making assumptions about how re-registration is handled which are probably wrong, based on my recent experience:
When I re-installed IronCAD after installing WinXP on my computer, it refused to launch claiming that it couldn't obtain a license. When I tried to re-run the license installation file, it said that the license was already installed. This suggests that even changing the OS will change the machine ID and render an IC5 license invalid. So far so bad. However, the good news was that when I re-registred IC5, I was sent a new license installation file instantly, apparently by an automatic license server which doesn't care if the same serial number has been registered previously. That's nice because it means I don't have to go and ask IronCAD LLC to clear my previous registration in order to re-register. On the other hand, IronCAD LLC has a record of how many times I've registred the same serial number and thus may choose to come back to me and ask me to account for it. If it's going to stay that way, that's a policy I can live with.
