Price, availability. For instance, steno software costed thousands of dollars. But this is about to change:
- Plover is a free, cross-platform steno software: https://www.youtube.com/watch?v=KZGuBV1xe64
- This Canadian guy develops cool, quality steno and ergonomic boards. The Georgi is $95USD - significantly less expensive than alternatives. There aren't any official reviews yet, but Plover users on Discord seem to really like it.

I'm planning to buy one this week - trying to get my boss to cover it since it will help with my mild RSI.
