It seems it is from each one's point of view.
For example, I wanted to purchase Ministry Of Rock and Voices Of Passion from Eastwest but there is no way I would get an iLok. I have Sonnox plugins for Powercore and they wanted me to get an iLok to get the latest versions. I never got it and I got stuck with the old ones instead.
For me iLok is way more problematic than Syncrosoft, and I find Syncrosoft very straightforward to use.
Apart from that, I use Cubase and Wavelab, as well as some VSTi's that require a syncrosoft key and if Vienna turned to iLok that would mean me carrying one more dongle on my laptop and a USB hub as well[:P]
I get your point but I am happy with Syncrosoft key here...
Well, I would be happier with Challenge/Response but life isn't perfect...
