I have a very specific disagreement with this article. I believe the research is sound and reasonable for most apps, but in the case of ShareMouse, they are competing against an entrenched free product.

I use Synergy, and there are some issues with it, but for the most part it does what I need. At $25 I would opt for the ShareMouse's easier config and someone actively fixing bugs, but at $50 plus the pain of switching over, it's just not compelling.
