I also have a spare room and I have been making plans forever! It's big enough to be divided so I decided some day I will make a reading corner surrounded by books and the other area for my tech thingies.

I decided it cannot have an Internet computer in it, because I need an area to sort of inspire to listening to the radio or reading a book. I usually just turn on the comp and do everything on it, and I don't think it is good for me.
