Nothing last forever, even when they say it will. I remember when we bought the Adrenaline, DNA was meant to be 'future-proof', too. Windows 10 is very stable these days but I wish they'd concentrate on fundamentals like having a good up to date windows audio sub-system that doesn't require Asio (something like Mac), instead of icons and user interface experience wows.
