Jefftaz,
While I can't help you on the wireless, on there keyboard Sony vs Logitech, some of the issues are...
Sony...
1) RF Only, so you are pretty much stuck with using the Sony remote with the unit, period. The Logitech mini-keyboard does actually work well except it will not control your TV because of the way Sony's remote send the IR for the TV from the REMOTE itself and not the IR eyes.
2) It is not backlit. So if you are in a dimly lit area, be prepared to turn the lights on all the time to figure out where a button is. This is also because IMO the keys are poorly laid out and I think only the play button has any type of tacticle differential feel to it. So no easy way to tell what button you are on.
3) Since the remote was most likely designed for a TV with Google TV in it and not a blu-ray player, the remote sends out the TV IR commands via a little IR window ON THE REMOTE ITSELF and not the ir eyes. This makes it so the RF is useless for things like the volume, turning the TV on/off and TV inputs. You gotta aim it. This is also why the Logitech mini-keyboard will not control your TV... because it doesn't send out IR commands from the remote.
4) It's clicky loud. Press a button and everyone in the room will know you just did. So if you use it in the bedroom, your spouse may not like it if she's trying to sleep
Logitech Minuses
1. A big keyboard and not the handheld mini keyboard. If you want the small form factor of the Sony, you have to pony up another $130 for it, which now puts you at a HIGHER cost than the Sony and still no blu-ray player.
2. The keyboard with the Logitech is also not backlit, so once again, be prepared to turn the lights on, if you need a key.
3) The Logitech mini keypad($130 add on) has less dedicated keys than the Sony. On the Logitech you will be holding the FN key plus another key to do many of the functions that have dedicated keys on the Sony.
There two BIG pluses to the Logitech however. First, the Logitech Revue supports IR remotes via having the Harmony engine inside. So you can use a Harmony remote with it or even a third party remote IF you can get it to learn the logitech commands(I have a URC remote and and harmony so I can teach the URC remote the harmony commands). Second, the mini keyboard IS backlit.
If the Revue came with the mini keyboard instead of the large one, I would be seriously considering it. I want the small form factor and having to pony up another $130 for the mini keyboard on top of the $299 for the Revue, puts the total cost HIGHER that the Sony and I won't have a blu-ray player either.
I'm sure people have some other thoughts, but those are mine.
