Even though I technically have a more "appropriate" workspace available, I just don't like it. I piled a lot of my hardware in one corner of the bedroom, the bed in another, occasionally use a display to watch a movie in bed with the boyfriend. Surprisingly the noise has not yet been a problem, but the hardware in question is usually two laptops and a mac mini and a drobo, all typically pretty quiet. I have a monster of a tower for gaming, but that's usually not left on while we're sleeping.
It's all a matter of preference.
