Thanks again Keef, Pro. it is then. I hadn't considered needing 4GB of memory and had thought 3GB would do the job. What I hadn't considered was video conferencing; it may well be a function that I make more use of in the future.
What is your view on 32bit v 64bit, my understanding is that 32bit will do the job nicely and be more compatible with accessories.
It seems the home computers are higher specification due to the assumption they are more likely to be used for media apps. Also seems they represent better value for money?
