The IR on my Palm Tungsten E was Very usable as a remote, all the way across a decent sized house. I really miss that. (The software the I used on it, NoviiRemote or some such, also let it learn from other remotes and had an ok default library of codes for major brands' devices)
I would love to see an IR port like my Tungsten had on more devices, for that purpose (Since the only remotes I own that actually are Bluetooth are my Wiimotes)
