It would be a strange world if we were all the same, with the same tastes and likes/dislikes.
Or as my mum would say 'There's nowt so queer as folk'.
I think there is room in the world for a little experimentation and personalization, the plain beige PC box has had it's day.
My PC has an aluminium case because I like it.
The reason that washing machines are never customised, well I would have thought that was obvious. If you consider that it is generally men who like to customise their cars, bikes and now home built PC's, not women.
I really don't like the Tie Fighter though, what must his wife think or his friends ?
