Actually, LMI Ignition has a mouse that's very similar to PocketCloud. If I had to choose between them, I would lean towards the one with PocketCloud. But the LMI implementation is very good.
The major advantage to me for LMI Ignition is my existing installed base of LMI remote hosts. Plus, I find LMI Ignition to be very good for what I need to do. Adding the file transfer feature (missing in LMI free on my desktop PC) is a great bonus.
I would still like to take the time to take another look at ST. And I need to spend more time with PocketCloud Pro too, but I had to remove TightVNC and the PC companion on my desktop while I chase down an errant driver or whatever's causing an occasional BSOD.
