Isnt AOS4 subject to it's own legal issues with haage and partner anyway?...
No.
I dunno why everyone focuses on the AOS4/MOS said FUD ...when there is FUD about the AOS4/Haage&Partner thing anyway.
If there is, you're spreading it.
What does AOS4 have to do with H&P?
There is a dispute between AInc and H&P, but not about AOS4. It is true H&P would not release
their source code to the additions made to AOS 3.1 in 3.5 and 3.9, but in most cases those were programmed by third parties who were free to negotiate their own deal with Hyperion for AOS4. There's no dispute about any of that.
As for the Pegasos, if anyone thinks I'll spend 1,000 Euros on a system whose details are kept a close secret, then they've lost their marbles.
