One piece of feedback I can give regarding these (which are similar in looks to the full versions): My wife happened to love the control and being able to turn it on from the nightstand (overhead, and lamps on the dresser, etc). The units were not visible, and everything was great.
When I setup a controllinc and lamplincs for some lighted topiaries she had, which happened to to be placed near an outlet where the control would be seen, I got a very negative reaction.
Consider this if you have a discerning spouse... They are rather noticeable.
On the other hand, I think I understand why there are not any plug in modules: consider the issues with appliance lincs, and how can you 'ensure' that outlets are used for only lamps currently? Regardless if this is right or not, I'll solve the aesthetic problem with outlet modules when they are ready.
