No desk top computer?

[Neil Winchurst]

We have lived in a fairly small house for over 7 years now. It was quite
big enough for us, but we now seem to have acquired three grandchildren.
  I use one of the bedrooms as a study where I have my desktop computer.
With all the bits and pieces it takes up quite a lot of room so there is
a bit of a palaver when we have visitors. Hints have been dropped!!

So I am wondering about replacing the desktop with a (good sized) laptop
computer. This leads me on to wonder if any list members do not use a
desk top at all, and rely on a laptop only. Anyone? Anything to consider
if I go down that route?

Thanks

Neil
