I have accumulated a few computers over the years. Currently I have a desktop PC in our office, a new netbook which I use when I watch TV, and an old netbook which I keep in my bedroom to play on before going to sleep. Lately I have been using that computer in the bathroom too. Do you think it's weird to have a "crapper" device"? Anyone else willing to admit this?

sometimes i play my gameboy while taking a bath
It's not normal to have so many that you refer to it as a "crapper" device.
The sad thing is, I often write on this site while on the toliet and I find it relaxing to do so. So yes, you are fine. I would keep it to a smaller system like an older system or your laptop, I wouldn't put your brand new system in the bathroom.
