This is absolutely true for me as well - since working from home in Nov, I've noticed the quality of my work has gone up even more than the quantity because I can concentrate on just the output rather than being self-conscious about looking like I'm working during the runup to the output. As a designer, for example, I've hit stumbling blocks with certain layouts and now that I think about how I've often solved the problem, I'd probably get tossed to the curb as a weirdo from even the trendiest of open plan offices - I'll list all the UI elements on a sheet of paper, then go lie on the couch for an hour or so and mull them over in my head to let it marinate, maybe go to the corner coffeeshop to read the paper to get my mind off of the gig but with index cards and sharpies by my side in case an idea occurs. I can't isolate when or why, but sometimes that's way more productive than just staring at an empty screen or trolling through CSS gallery sites.
