Looking for a good IR blaster, preferably wifi enabled, for the iPhone and iPad. Needs to control my TV (samsung), receiver(Sony), cable box (scientific atlantic) and maybe my mac mini. I've see the Dijit and Roomie. Does anybody have any experience with these? I'd like to get rid of all my remotes if possible. Plus I feel it will make it a lot less complicated for my girlfriend as the universal remote we have now confuses her.
