Impressive.
But, an expensive handpiece.
Also you still have to use track power. Once someone gets them to work on batteries in the loco, I would definitely be interested.
Polk’s Revo uses a “cell phone” like transmitter.
Looks like he’s already behind in tech know-how. 
Myself, I’ll stick with the easy stuff.
This is very cool but as Tony said that’s one expensive hand controller. But think of this, your wife can call you and tell you to stop at the store for something and you can check your email while operating your trains!
I really like the demo in the first video. The 1:32 scale European stuff is very very appealing.

BTW guys, those who don’t want their wife to “butt in” can choose the iPod instead. Teach your trains to boogie!
I added a web server to my transmitter as an experiment about 8 months ago. It allowed any web device to connect and operate any of the 32 locos controlled by the transmitter. I’m not an expert at web design so my browser interface wasn’t so pleasant to use but it could work on a number of mobile devices. The prototype was wired ethernet but a final version might have been wifi. That code is not in the current transmitter version but the basic hardware interface is still available. I decided to concentrate my work on Back EMF for slow speed operation so the external interface was relegated to the shelf. Oh, while locos were controlled via the web, the transmitter could still be operated normally, except that it had an ethernet cable attached
That’s brilliant. I don’t even have a cellphone, and I think that’s really cool.
And then how about the new IPad thingie ! Which is claimed to surpass the iphone boy there must have been a stampede for those by the apple/mac groupies including others who just buy the latest toys so they can say they got them !

also not a cell phone owner !

I think you can do it with an I-Pod as well. A customer told me his son has an I-Pod that “talks” to a computer with WiFi.
