Timed thermostats have the issue that you have to know what time you're going to be there. Some days I'm home at 1800, other days I won't get home until 2200, and I often won't know until sometime during the day. Now, I don't use heating, so it's not an issue for me, but I could foresee it being an issue. The ability to use your phone as a universal remote is alluring as well. Being able to control the lights, TV, and heating all with one device is pretty cool.
