I've got my entire recipe DB on mine and I cook from it all the time. LOVE it! Yesterday the whole arrangement got even better when I got this nifty frame that mounts my iPad to an overhead cabinet.
This places it solidly at eye level and off the counter where it takes up precious space and gets glommed with powdery and greasy things.
At $50 it's not cheap for a tiny bit of metal and plastic but it does the job, holding the iPad securely and going onto and off of the cabinet effortlessly.
Belkin makes two other options. See all of them here: http://www.macstories.net/news/get-co...
Hope it makes someone else's cooking and baking more fun and convenient too.
