Asterion,
Although you are very disappointed, I wonder why. I have another computer music friend that I have known very well since high school, he feels the same way about the dongle.
He came over to my house and I showed him some music that I was working on, he was very impressed with the Arturia software, and soon ordered some.
He knew about the presence of the dongle, but somehow it made no difference to him, which surprised me.
It is agreed that dongles are bad things by themselves, they add clutter and more issues with the usb hubs.
You should also consider why they are used in the first place.
Copy protection is an issue, especially now that we live in the high speed internet age where any kid can find a hacked version out there for free, its just not fair to the developer.
This software is there creation, therefore, IMHO they have a critical choice to make about how to protect the software.
Personally, the sound and practicality of this software outweighs the impact the dongle makes on my computer.
If the dongle protects the software from being stolen, then that is a good thing. It will help Arturia stay profitable so that they can keep making improvements to their paying customers.
Take the good with the bad, everything comes with a price. IMO, there is far more good to the dongle than meets the eye/usb cable.
