After I was just done with all the struggle required to buy a good PC, the keyboard and mouse combo I had chosen was Logitech Cordless Desktop® MX 3200 Laser.
But sadly that set was crappy and all others that he showed, so I returned that back to dealer and took money back. Then I started searching for some simple keyboard and with a bit (or byte ? 
) of help from Aman, settled for Logitech NewTouch™ Keyboard 200 (USB) (Just feel, how sweet it sounds from the name 
)
The biggest problems with this keyboard are the small size, bigger Return key and pipe key moved in upper row. All the crap. So again the time to look for a new keyboard. Never even get moved by the fancy terms used in the name. Please do read reviews on Amazon and then only move to buy the stuff. Not much useful post it may be, just wanted to let out some frustration 
.

all of them look great so budget is the next question
I like S520 cause I have its daddy the previous S510
Man i dont like the design of Return key in this. Wireless things are too costly. I guess need to settle for good wired one
. Any hits ? 
I dont condone the use of wires
DDDD
