Anyway, I'm now using the new Mac, and very speedy it is too - except when my wireless signal appears to fail, as it has done a couple of times this evening. Don't know if this is a hiccup in the Airport or at this end, but time will doubtless tell. I love the big shiny screen, which allows me to see what I've got open far more readily than the small screen; I love its brightness and its wonderful colour rendition. And the keyboard is a joy - the low-profile click of the laptop with the ergonomically more pleasing position on the desk which I am now sitting higher above. Whatever is doing it, my typing speed seems to have improved already.
I still have some moving around to do - the desk is tidier than it has been in years, and I had to clean the dust of ages to allow the mouse to function (still getting used to the mouse, BTW). I can't see one of the pictures above my desk and will have to move it up the wall. But I'm a happy bunny nonetheless. Cheers!
