I'm still little confused. From what I understand K400R is same K400 with latest software supporting windows 8. But latest software is also available for k400. So is the only thing that K400R comes preinstalled with windows 8 software and in K400 we have to install latest software itself .

Yes, both keyboards, the Wireless Touch Keyboard K400r and the Wireless Touch Keyboard K400, are supported on Windows 8 however K400 was manufactured before Windows 8 came out and the K400r was manufactured after.

Logitech changed the K400 to K400r without any notice.
K400 works like a charm, a small cheap useful keyboard. The included drivers aren't even needed for it to run, not even needed for all the buttons on the key-board if you have windows. (Linux might be another issue, but as far as I know, it works with Debian LXDE without any issues.)
K400R does look the same, however...
Function keys (F1 to F12), doesn't work if you don't hold down the FN key. This makes the keyboard useless for gaming and or anything else that requires you to use F keys. So the K400R is NOT a one hand keyboard (for those that only have use of one hand)
The included CD gives you 54MB of nonsense, better just download the Unify tool because that's the only thing that works.
You cannot change the behavior of the F keys. You can however change the behavior of the mouspad features, by holding down FN and press on right or left mousebutton (to turn on, off different features), you don't need anything from the CD for that though.
The K400 had the Pause key, K400R doesn't.
(Note, some shortcut functions works as they should, ALT+F4 still closes the current application, so that's good I guess. You don't need to be an octopus, and hold down FN+ALT+F4.)
Oh, and be careful when using the keyboard inside a UEFI, if you don't remember to hold down the FN key for Function, you will get some extremely annoying "mouse movement and random clicks", that can mess up everything..
I did ask ASUS about it, and they just said "Logitech k400R? Don't use it when working in UEFI, we have reports of that keyboard, and we can't do anything. We are following the standards."
But a short answer to your question, No.
There are hardware differences between the keyboards. Even though the drivers might be the same, the keyboard buttons aren't. The K400 also lacks the "pinch zoom" thingy on the mousepad. The K400 also doesn't rightclick when using 2 fingers. (The 2 finger scroll are the same though)
(If you don't have Win8, don't bother using the K400r, try to find the K400 (K400 have the old widows-logo on the keyboards win-key )

Wait, so to support a meager couple of extra features which aren't even Windows 8 specific, and have been default in multitouch pads for years, like pinch to zoom and two-finger right click, the k400's hardware needed to be "revised"? Why can't this be done in software?

I realize that Logithech doesn't claim that the K400r will connect to Android. However, I've seen several web commentors that say they've connected their k400 to Android. The unit that I bought is not recognized by my Android phone (running Android 4.05) or by my Nexus tablet (running Android 4.2). I have a functioning OTG adapter cable and I verified that a (big and clunky) Microsoft wireless USB keyboard/mouse combination will connect on both devices. I also verified that the unit I bought is recognized and works on my Windows 7 PC. I could really grow to love this small, light keyboard. IS THERE ANYTHING THAT I CAN DO TO CONNECT MY K400r TO MY ANDROID TABLET?
