I will admit that popularity was a key consideration in my selection of Studio One for my main DAW. Is it perfect? No, but I expect it to improve. Popularity means to me that a product will continue to sell well, be continuously developed, and have a large community of support. Factors that one would hope should offer an opportunity for a lengthy product lifetime.
My DAW selection criteria basically was this:
Must be cross-platform. There were a few other options that were Windows only, but passed on them because I did not want to deal with that limitation again. IMHO that may have impacted Sonar's marketability and perception.
Must have an active community and well supported, and not one of the "other" DAWs.
Must be cost effective. The special crossgrade price was stupid low.
Must meet my needs. I work with MIDI mostly, but have retired my external synths. S1 appears to do what I need with virtual instruments, and the plugins I have seem to work so far. I have Overture, but may pick up Notion for the $49 deal.
I also have a few other DAW-like programs, but view them more as idea starters. Not things where I would really want to attempt a project mix down in. Would really have preferred Sonar lifetime for that, but oh well...
