I think Neil made my point - like they used to say about wireless - the pictures are so much more vivid than they ever are on the TV.

I could be watching all kinds of spectacular stuff happening on the TV right now, with a drink in my hand, if I wanted. So instead I'm sitting up here looking at a screen with words typed on it, and taking my time making my contribution. Noone's going to interrupt me while I'm saying it. It's custom made for boring old farts like me -and with an aging population there's more of us around every year from now on.
