For me it's a winner.
I have been using RDM+ since 'the old days' and always found it little slow and hard on a small screen, but now that I am on the STORM2 it is much better. Very Acceptable. It does what I need. The bigger screen is great and the REVA speed makes it fast. Its speed is limited to the fact that when you show something on your phone that it hasn't been shown before, RDM+ needs to send the screen over the airwaves to your phone. Also, all commands need to be sent back from your phone, to the computer, executed, and sent back to the phone with a screen refresh. That is no easy task.
Of course, there would be no way to turn on a computer that has the power OFF but you can reboot a computer from remote.
