So are they going to neglect the Keynote Remote? I mean that app hasn't been updated in 2 years. Let alone has retina display compatibility or iPhone 5 screen compatibility!
Even with such functionality, it seems complicated and limited, esp compared to a traditional TV remote. Why the heck can't Apple just put a vertical virtual slider up/down the whole side? (Sometimes it is necessary to quickly adjust volume on the fly, as well as hit a mute button; not having this done easy is very incomplete.)
