I always use my N900's IR with Pierogi to control my TV and cable box.

LED notification is priceless.

I can't believe I'm going to say it, but battery life on the N900 has been far far better for me. Not once did I have to mix in with the crowd of iOS and Android users all huddled up around the 2 available power outlets at the numerous airport terminals I've been to even after a full days use with just 1 battery. Also, having the ability to replace my battery when the current one runs out is a he'll of a lot better than having to "plug in" to an external battery pack.
