i had a play with the one on the gaugemaster stand with my iphone4 and ipad2 and ive got to say im very impressed, the gaugemaster guys let me do all sorts with the system, programmed locos, took photos of loco for roster, set up the accessory decoder to control points , photographed the layout and moved round the points icons to suit, all of which i managed to do within a couple of minutes of joining their network
i'd already set my heart on one before warley but i have a few niggling doubts about it before i commit to getting one, my main one is that i'd be buying one for the gimmic factor and i could end up with an out of date system after a year or so should the company decide not to develop the system any futher, as it stands now the system cannot do route setting, detection etc, hopefully with futher updates that may appear in the future but if it didnt happen then i'd be stuck
one thing id like to see it do would be to be able to have an ip addressed camera feed on a loco that could be streamed to the pad/pod/apple tv etc so you get a drivers eye view of your layout, maybe add a few uk loco cab interiors to the drivers view function
once my new layout is up and running in the shed i think ill be getting one anyway
