If it's just about where you play games or sit while using the computer, you might try a wireless keyboard.
Right now, I'm lying full length on my settae about six feet away from my computer listening to Hal through my speakers typing on my wireless keyboard. I can even play games over here lying down sinse my headphones have a long cable, or write my thesis.
should I decide to go and get some coffee in my kitchin, I can even take my keyboard with me.
Some models are better than others, but a good bog standard one is as responsive as any other keyboard, but has the advantage of letting you be anywhere you wish to be within range of your pc, ---- and the range is pretty good, at least 12 feet or so.
If (as i probably will in summer), I decide to go out on to the balcony to use my computer, play games or whatever, I'll take my laptop as I will tomorrow when i have a long train journey, but for just mobility inside my flat and being able to sit (or at this moment Lie on my back), where I like while on the computer my wireless keyboard does very well.
Btw, this is actually one of the few advantages of having a screen reader. I can write my thesis, use the net, play games etc without looking at the screen at all, thus do not even need to face the tv, let alone sit anywhere.
in fact, I only turn my monitor on if I am doing something which requires me to look at it such as watching dvds or playing graphical games.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
