A toaster is an appliance..
..and yet, most toasters come with configurable options. You can decide how brown you would like your toast. More advanced toasters will take many sizes of bread, right up to self-baked, self-sliced doorsteps; the ultimate in home-brew. If the fuse goes pop, you can usually unscrew the plug (or flip the flap underneath if it's a crappy moulded thing) and fit a new fuse. You're not limited to what type of bread you put in, nor what manufacturer it comes from. You can even get third-party add-ons (ever hear of "toaster bags"?) that allow you to make things like cheese toasties, without getting an awful mess on the crumb tray.
Another appliance is a fridge freezer. Did you know a lot of fridges allow you to configure how much power they use? Many allow you to take the shelving out and reorganise it as you, rather than the manufacturer, wishes. Hell, if you don't want that whacking great meat drawer at the bottom taking up space, there's nothing in the EULA saying you have to have it there. You don't get Hoover or Smeg saying that you can only freeze approved water in the icecube maker, and I don't think they'd be too bothered if you used it to freeze non-food items.
If you don't care what your toast comes out looking like, and just simply plug the thing in, bung some bread in and depress the lever then good for you. Same if you're happy with the fridge shelves as they are. Some of us, however, would rather be able to manage our "appliances", especially when those appliances are computers, being sold as computers (sorry, "new computing paradigms"), with all of the configurability that this implies.
Trying to make this as not-a-flame as I can, but.. dammit, the "appliance" argument is a really shitty excuse to let Apple get away with selling locked-down crap.
