Dell U2414M monitor connected to either a linux base unit or Dell XPS laptop that I use for photo editing. I'm not happy either editing or viewing images for crit on anything else: the XPS makes everything look better than it really is (the Macbook make it look odd) and I don't use smaller devices than a laptop for looking at photos. Your ipad makes things look better because of the fine dot pitch and the smaller screen that hides flaws, just like my XPS.
