I like PT because after a little setting up I can get a stable system. When there is a problem its quite simple to track it down as there are less variables that a multitude of ASIO interfaces would introduce.
Well, that's true, especially for TDM/HD setups. Unquestionably worth it. I fully rationalize the architectural differences from ASIO to TDM, but I doubt that LE and MP are really much different, technically speaking. I would not be an authority on that subject though, just my guess.
I don't mean to imply that Digidesign should stop developing HD, LE, MP by any means. I suppose they could broaden their line up even more and offer an ASIO version, at yet another price point. This would preserve those lines, and also tap into the broader DAW market. Just an idea. I doubt it would happen.
Come to think about it, it might work better for them to include PT with M-Audio hardware as they do their own interfaces. Then leverage that by offering the ASIO release at the same price point they offer MP at now, thus keeping the M-Audios more attractive than other ASIO cards.
