Ableton is an overpriced piece of shmoo that will soon go away. It has over extended its welcome.
Ableton is amazing. I keep coming back to it. I've used it as my daily driver since version 3 (pirated) and I've paid for it since version 6.
It would be awesome to have a Linux version (aside from the headless one in the Push 3 standalone) and it would be awesome to have a native SDK for device development, and it would be extra awesome if they open sourced it (never going to happen, but I can dream).
It's cool if you don't like it, but don't tell other people what they should or shouldn't use. You can offer alternatives, but just telling people they're wrong is arrogant and unhelpful.
Don't shove things I didn't say in my mouth and call me arrogant.
