X10 sure does like to send out e-mails. I just gave them my "spam" account address. Sometimes they have really good deals, although not as good as they used to. 🙁 They used to have free shipping on everything, and they would send out $10-$20 gift certificates nearly every other week. All of the lights and switches I commonly use in my house have been automated, I have 2 MouseRemotes, several "universal" remotes, and hehe, a huge stockpile (like, more than 20 items) of X10 lighting and other modules and accessories that I got for free during their promo heydays but haven't found a use for - yet.
But anyways, the point is the X10 MouseRemote MK19A + maX10 software is hands-down the best solution for remote-controlling your PC.
