I just don't subscribe to 100% tested as a statement of confidence without qualifying what 100% means. "We have certified to 100% of our Design Verification Standards", would be how I'd post it. In software, we've learned in the past that even the most heavily tested software isn't perfect by any means, but is highly unlikely to draw issues for expected less than 1% of users. Even so, hardware is so diverse, that even IEEE standards are never perfectly implemented. Microsoft can't honestly say their software is perfect yet so I couldn't imagine Sonar being perfect in Windows8.1, let alone 10. With that said, I'm glad to see Cakewalk preemptively giving Windows10 a thumbs up and with some bonus points!! Well done!!
