With the Splashtop Business model,a single user can login to the several machines assigned to that user in the Splashtop account. Currently, a "pro" plan user can remotely access 10 different computers. To add additional hosts, you would have to purchase additional "users" to be able to assign those additional computers. LogMeIn is host-based-- pay-per-host makes sense with a server that many users will be accessing. Splashtop is user based-- pay-per-user makes sense when one user needs access to several servers.
When I started using Splashtop, I recall that it was $60/yr for 50 hosts. That changed to $60/yr for 10 hosts a couple years ago. And it looks like Splashtop just recently changed/segmented its pricing when it added new features. Before August 20, 2018, the pricing was $60/yr for one user to access up to 10 computers. This is now cut to 2 computers, and a $99/yr plan has been added with updated features and allowing for up to 10 computers. (For existing users, it looks like the $60/yr, 10 PC pricing is grandfathered provided the new features aren't required.)
Splashtop isn't immune to pricing tweaks, but they aren't nearly the jaw-dropping levels of LogMeIn price increases.
