are cordless keyboard available

COrdless peripherals are available for use, but i guess they do cost more. They are not so popular among gamers or graphic designers. I believe those devices are also sensitive to signals detering the communication between the pc and teh devices. So if you want to buy make sure you get a good brand, and also it is what you need and want.

yep they exist.. go to some electronic stores or websites and you will find them

i too would like to buy one, do letme know if its avaialable

Yeah it's already available for a long time, it's already common to others (even me). But you have to charge it's battery everytime the battery depleted, but it's handy especially for Media Center PC's and who use PC's in their room with huge Widescreen LCD while they are in bed.

Absolutely. I use a laptop at work and it can be very uncomfortable after a few hours. I just got a wireless keyboard and mouse for $29.00 US and it is great. No more back ache and I can sit in the most comfortable position and still have easy access to my keyboard and mouse.

YES

cordless key boards are also avialable both IR as well Blue-tooth.

you should have either IR or blue tooth connectivity on your PC to use those kind of KBD

Sure, they've been available for many years now.
They are also not very expensive. I bought an A4-tech set about 5yrs ago which was really good. I got about 10m distance with the keyboard. I didnt need that far, but i was testing its limits.

I currently have a Belkin set (never thought i'd admit that), which does ok, but only gives about 1m distance at the best of times. Also i get regular problems where it just dies and needs to be re-synched or adjusted. This is a pain if i'm gaming.

Wireless sets are really handy for space-saving and for being lazy and sitting back in a chair whilst using PC;)
