Yeah, checked that out. It's pretty big and clunky, and requires that you stick a dongle into the computer. Not clean at all.
I'm puzzled as to why the remotes don't just use bluetooth. Satechi has a bluetooth one that works great, but only for Keynote - it does not work with PowerPoint (why they didn't just support both is beyond me).
If any hardware vendors are out there, creating a remote that did nothing but pretend to be a bluetooth keyboard that hit the forward arrow and back arrow would be brilliant.
I am incredibly frustrated by the fact the macbook has no IR anymore. It really makes life more difficult as I use it often for photoshows, on entirely remote areas and I hate to have lots of stuff with me.
And no, IPhone is no option, as I dont rely on the WifiConnection. Its just not safe and professional.
So: I bought this:
and use my old remote again.
I wonder when I lose the dongle.
Just another thing to worry.
Agree with the C for the Retina.
For the sake of others who might read this thread.
What I usually do if I can't get to a wifi router, is simply have my laptop create a private network (using the "Create network" option from the wifi menu in the Finder). Then I join my phone to that network and use that setup to remotely control the keynote presentation.
You won't have access to the internet while running your presentation but with the presentations I've given that's not really been a problem.
