Yeah it seems neat but, I guess I have become old and crotchety because once the wow factor wears off it seems more trouble than it's worth.
Say I am sitting on the couch and want to turn off the light.
1) Get phone out. (If I was lucky enough to have my phone in my pocket.)
2) Unlock phone
3) Find WeMo app
4) Start app
5) Wait for app to find and update light bulb status.
6) Press screen
7) Wait up to 10 seconds for light to turn off

1) Get my axx off the couch
2) Walk over to light switch
3) Flip switch
The WeMo phone interface seems nowhere near as convent as my old X10 system. I had a universal remote that not only controlled my entire entertainment system but also all my X10 modules. I could pick up the remote press one or two buttons and dim the lights, the press another button and start playing a movie.
The real problem is if the lights are off by WeMo then I have to find my phone to turn them on (X10 had a bypass). Sometimes that is easier said than done (I know, shocking for the young-uns)
I often have to call it and listen for the ringer. If the phone is dead then I would have to charge it first just to turn on a light.
I guess the draw is being able to turn on lights when not at home or setup a schedule.
