Lee are you watching the same video I am? Put your glasses on. First off he is going slow enough to hide the lag. And you say no visible lag. Do you not see where he scrolls the android phone left and right the lag? I don't know about you but I call that visible lag. I have used team viewer plenty of times between my phone and my computer. I used to control my presonus that way before i got my iPad. Yes there is a very noticeable lag. But it never made it difficult to use. But, none the less, there is most definitely a lag.
