How about this as a use-case [for a tablet].
Attach it to the wall by the front door so I can see how my trains are running and if I need my umbrella as I leave the house in the morning.
Not saying I’d pay $500 for one but it’s certainly something I’ve considered building for my own use.
2lmc had a computer, called spoon, that had a touch screen and sat in the kitchen, showing news headlines, the weather and the state of the Tube. It was sort of nice, but the fact I’ve never bothered to recreate it since seems to imply that the whole “fridge screen” idea isn’t going to be a huge seller. I suppose I could be wrong, but if Apple suggest that’s the use for their $500+ tablet, I’ll be amazed.
