In my comment, I mentioned that "everyone likes a little dessert," but I think it is a great analogy to how difficult it is (still, unfortunately) for tech coaches/facilitators, etc., to get "those teachers" to use technology. But, if it's done right, you'll get them to come back to your buffet or maybe even leave a tip.
While we here at the Tech Fridge like the analogy Darren used, we think that you could also use a Tech Fridge in your analogy. Your tech fridge is filled with those technology items that you most rely on, that you are willing to share with friends, the best of the best. Just like going to the grocery store: you don't buy everything, just what works best for you. Tech Fridge's are highly valuable, you know :)
