I have one Desktop & Laptop here although there is another of each in our flat.
Son has a Desktop with recently kaput GFX so he`s been using a spare laptop for the last couple of weeks.
2 Oldest daughters have Netbooks while the youngest 2, and their mum, share a laptop set up in the sitting room for them.
It wasn`t that long ago i actually began using computers but it really wasn`t much long after that the wife found herself threatening to leave me if the number of computers i had ever outnumbered the 5 children we have.

If you count the 2 broken laptops out in the shed though then i`ve managed to double the number in question and she`s still here. It`s actually down on what it has been at times so she cant really complain eh.
