Besides, no well prepared meal is complete without a pic of the completed work uploaded to facebook :-) .
Also, a single recipe is fairly easy to follow, handling a few a the same time is where a computer could actually be useful.
I could also make use of a touchscreen splashback showing either general entertainment or recipes where I could strike off ingredients or steps as they were completed. Saves having the iPad or a book taking up bench space.
Could have touchscreen in one area and then display with heat-resistant glass behind the cooktop. Maybe in 10 years time.
[1] My wife would use her iPad more for this if she could write notes on it. I'm looking at a Note pro for that application, and of course being able to pull up info from the filer rather than the 'cloud'.
