Melikia,
That sounds encouraging. Yep, definitely a mouse.

Mari-anne,
i had considered this, but I have already taken over a whole room for my computing stuff and the look on wifeys face when I mentioned moving into the living room as well was not encouraging. There wouldnt be a problem if I could find a LARGE office chair in the UK but I`ve had no luck so far. Found one that was rated for 40 stone, (about 500 lbs) but the seat  was 18"  wide. Like to see the guy that was made for. 

bruno,
Thats slightly less spec than one i was lookimg at so it would seem there is no problem there. Now I dont know wether to wait until the Windows 7 models hit the stores. Sounds  sensible.

Thanks for the replies.
