Be careful, the neck position may catch up to you eventually! I spent about 75% of the workday in bed with my laptop over the past 5 years. Earlier this year, I experienced my first pinched nerve - chronic pain is horrible; the doctor, medication, and especially the physical therapy are no fun :)

I recently started using a lap desk laptop stand with multiple adjustable angles and comfortable bolster cushion (in case you're curious, the brand I purchased is Halter - $19.99). I now sit on my couch with the laptop screen directly in line with my eyes, to prevent the typical downward neck tilt common with desk use.
