Can the family sedan boast 500 Horsepower and run the quarter mile in under 14 seconds? Who cares, when the family sedan meets all of their current needs, and 300 of that horsepower will go UN-USED on a day-to-day basis.
It depends on the USER's NEEDS, doesn't it? Most functions on a remote are used once, and if not once, so sparingly that they are unimportant in day to day use. Those that are used commonly are usable from most any remote these days.
I use a single (my Mitsubishi TV) remote to control all of my components, including by PS3. My son uses a single (his Onkyo) remote to control all of his components, and he has over $xx,000 invested in his system.
If one has Cable, Satellite, or some other content provider, after a TV is initially setup, all that is ever required is to turn it on and off and maybe adjust volume. Volume control is unnecessary if one is using an A/V receiver, as the OP is doing (although most remotes can adjust many functions on the TV, including changing channels, usually on and off is all that is required).
Once a set-top box is installed, one needs to turn it on and off and change channels, access menus, etc. Can the Onkyo remote do all that? Yes (as can most remotes).
Once a DVD/Bluray player is installed, one needs to turn it on and off and access menus, play, pause, etc. Can the Onkyo remote do all that? Yes (as can most remotes).
Once a PS3 is installed, one needs to turn it on and off and access menus, play, pause, etc to play movies. Can the Onkyo remote do all that? Yes (as can my TV remote, all thanks to CEC).
Can the Onkyo remote control EVERYTHING on these components? Who cares? Why spend additional money for something one doesn't use? I set my Onkyo receiver and leave it alone, that's why I use my TV remote for everything. My son likes to fiddle with his surround settings, so he uses his Onkyo remote for everything.
As I said, Harmony remotes were a great idea, back in the day, when no manufacturer's remote would control another's device. Some may still find their current remotes lacking, and need a Harmony even today for some applications. However, it is no longer a necessary or cost effective purchase for most people. I personally have been using a single remote for at least 10 years, with no need for a Harmony.
Based on the OP's setup, his Onkyo remote is capable of controlling everything he desires. That is the point of my posts. If he (or anyone) wants to continue to use the Harmony, I'm all for it. Like I said before, it's ain't my house.
Again, YMMV, IMO, No polar bears were harmed in the production of this post, etc
