We have a family desktop, but it seldom sees any use these days (in fact its set up in the loft).
The printer is networked, I have portable DVD/CDRW drive and HDD and everyone uses a netbook, the wife has a Dell Mini 10 (which the battery is karked on after just 18 months), I have a Samsung N130 (but has lousy speakers) and the lad has an Acer something or other that is on semi permanent loan from school - all 10" screens and all work well enough for what we want ( I finished off a research paper on mine with no problems at all).
