I'm new to the Beo5, I've only had it for 2-3 weeks now. I have to say, though, that I love it! Sure, it needs to be charged, but hey, instead of throwing a remote on the coffee table, I place it in its charger instead.
The Beo4 is a great remote, no doubt, and I'm sure there are those that used it much more extensively than I did/do. I only used it to select a source and turn volume up/down and that's about it. Much to my fiancee's disappointment, all the other equipment remotes were on the coffee table too! Not any more...with the Beo5, I've now got control of my entire system. I did have to post a few questions here on this list, but the programming was a snap and none was done by the dealer...did it all myself and have a very customized remote.
On my main screen I've got all my sources...TV, HD-DVD, Blu-Ray DVD, Escient, DVR, PC, Radio & CD as well as a switch-over to the projector from the TV.
Love the feel of the remote in my hand and do most things singlehandedly.
