It has a color touchscreen which is simple for guests to operate.I also have 2 Digital Watchdog exterior cameras so I can keep an eye on who is coming and going and monitor when the house is between occupants.

(A nice personal touch)For thermostats, I use the Honeywell product line (non-touchscreen), and I've been happy. 

My 2014 model has a touch screen, great sound system, lots of legroom, and surprising storage.

Marble countertops, polished concrete floor, full body shower, touch screen bathroom sink for the ladies.  20 minute drive from a million population metroplex.4. 

The stupid touch screen wasn't working right, so when you touched one "button", the "button" next to it registered the input.

Set it to cool down the place just before I'd get home from work.http://www.homedepot.com/p/Lux-7-Day-Touchscreen-U...Something else that really helps keep the place cooler, is to run a large floor fan, like this:http://www.pattonproducts.com/fans/patton-18-inch-...They make different sizes.  

I have two Honeywell 9000 color wifi touchscreen thermostats.
