I also purchased a touchscreen a few weeks ago, and I'm currently working on some software that will let you do this. It looks pretty slick, like Creston (I too found that most available programs have extremely tacky interfaces)... I think you will like it a lot. Right now it has an mp3 player, tv tuner, email/web, x10, x10 superRemote, caller id, and a few other features. The next step is to have it control my theater... I am looking for a good IR device, might get the RedHat2 (
[Link: dodgies.demon.co.uk]). Any suggestions? If I can get a device by this weekend, I can have IR and macros, etc in the program within a week or two. Anyway, send me an email and I can give you more information (screenshots, etc).
By the way, I also have a pretty nice TiVo-style mp3 player. It uses the X10 superRemote and has a TiVO-like interface, playlists, crossfading, tv tuner, etc... I have it hooked up to my tv in the living room. I'll try to post some screenshots of everything soon.
