I have lots of software on iLok - for me its really handy - as I live in two different Countries and have multiple systems in both (oh and a laptop!) I install on everything; I have no authorizations worries - just take along and plug in my iLok where I want to work at that time - and if I have a Computer melt down, just unplug the iLoks, plug them into one of the other systems and you're back up.
The system used to be total crap, but it really has improved in my experience in the past couple of years
