How can I use a desktop like a laptop [closed]

I am not looking for a remote control application.

I need a new computer. Typically I buy desktop-replacement laptops and use them in the exact same location (my couch).

I would like to save $ and gain upgradability by using a desktop, but still be able to use it from my couch.

Is there any sort of "stub" laptop with just a keyboard and screen that I can (wirelessly/wired) connect to a tower sitting next to the couch?

How about some sort of "lap stand" for the monitor?, as trying to balance a normal monitor on my lap seems like a quick path to failure.

Solution 1:

Yes, its called a wireless keyboard/mouse and a long cable for your screen :)

Or, you could buy a cheap netbook and use VNC to export the desktop's screen to the netbook.
