I couldn't help but chime in on this one, since I JUST finished a trial of PT11. Here's my personal take:
PT is analogous to Photoshop from Adobe. It's like the Kingpin of the DAW's and very widely used in studios world-wide as well as many thousands of home studios. Adobe products are similar here. However, there's one major, and I mean MAJOR flaw to such a tool. Being one of the first, if not the first full-fledged DAW on the market, and developed on a Mac, it's not easy to evolve it. After the pro's become efficient with its workflow, Avid would be making a huge mistake if they suddenly changed it. Undoubtedly, the code it's written on must be old, because it's not the most efficient use of resources, and you'd be hard-pressed to simply re-write the old engine.
I believe, from my trials, PT is one of the most non-intuitive DAW's on the market, but why does it still succeed? It's Grossly key-stroke laden, to the point of multiple maps you can switch to. Users very quick with key-strokes rarely ever need a mouse. They work much faster than a mouse can afford them, using keys, so this provision must remain the norm. ProTools scalability is vast, considering all the hardware it can seamlessly integrate, giving you more than 150 channels with little to no latency. The power is there, but what about the evolution? Seriously, when I see an installer in 2013 that pops open several MS-DOS prompts, I'm holding the software in contempt. That is a red-flag and dead-giveaway that this code has been converted, and not naturally written for Windows.
Speaking of mice, PT isn't savvy with Right-click like other DAW's. I believe this was largely because Mac's of the last decade were single-button mice. I also believe that in all Steve Job's wisdom we have a Photoshop that is still, to this day relatively non-intuitive, catering only to professionals who have training.
My opinion of PT is that it's trapped and on life-support. It will be so difficult to change it drastically for the times, and the company's HQ as you can see with lack of direct contact are not interested in feedback from everyday users. If you are going into the industry and will absolutely be required to know ProTools, learn it and pay dearly for it. I'm sure it's ROCK SOLID after all these years of working out kinks, but my money is staying with Cakewalk, since it is far easier to use for me, and many studios are apparently providing Producers with their choice of DAW, vs. only supporting PT.
One last comment. Avid is on my $**tlist because of RTAS/AAX. I pay WUP to Waves to get the latest updates when they become available. Since PT users demanded AAX from Waves, and Waves had to respond, Avid requires AAX for PT11. They don't offer RTAS support in PT11. Their workaround is the archaic, give them a free license for PT10. I'm sorry but that's an amateur's band-aid for a problem created by themselves---and I had to pay for it through WUP. So, I have a beef with Avid for that one.
