Use Cases and Deployment Scope
I use Splashtop SOS to provide support to my clients, and Splashtop Business to access my home server from anywhere in the world I happen to be. I've been very happy with both, and I've recommended Splashtop Business to multiple clients. I had previously used TeamViewer in both roles. Splashtop has all the features I need (multiple monitor support, shared clipboard, drag-and-drop file transfers, support for multiple OSs, per-client logging, you name it); it's much more affordable, AND Slashtop customer service is much nicer to deal with if you ever need it.
