Why would you need the K4. Ohh in case you want to cue video. Control anything else with a GUI that you made. Maybe see composite cameras. Control a matrix switch. Minor web browsing like XML weather pages. ETC ETC.There are lots of reasons to want to use a different touch panel then the touchlinxs.

Now the new bigger touchlinxs... that should have a wow factor. But the lack of the features above still makes me look to the RTI.

I agree.

I do not understand why RTI only used a "B" speed network card. Every other mfg of wireless devices uses a G as a min, For example Pronto, and other are incorporating "draft N". If there was a "G" this would make things much better. Of course thats why I wanted somone to see how fast the pages come up on the K4 becuase its the same processor, etc as the T4,> Only difference is a hardwire netwrok vs. a "B" wireless.
