I can get on Amplitube as see what I own, all my products I purchased. I can aslo see what I don't own (which ain't much)
I can do the same on TrackS.
As far as the IK mobile products, I recommend them all the time. And from what I am gathering from people like the Pianist53, the mobile customers outweigh the older customers. Hence the reason (understandably) that they devote most of their resources to mobile development. The mobile customers are the existing customers!
The only thing I paid full price for was the Mesa collection. Due to my own neglect. In fact, if I had to give up all my Amplitube stuff and only keep one thing, it would be the Mesa stuff. Most of the other collections I have, and I have all the major stuff, I don't use. But I got them for almost nothing!! So no loss really.
And I have no problem buying from the custom shop with Gear Credit or Jam Points. But I did have to take a lesson on how to do it. (Thanks CW Forum!) And once I learned how to do it, I saw all of the instructions wrote exactly the way they told me to do it on IK website! Why didn't I see it before? IDK. That's part of the problem though.
