I Have a cheap Keurig singe serve coffee maker and I love it but hate it. It has only two cup sizes and no control over temperature.
My dream would be for it to have a micro controller installed so I can have multiple sizes including a travel mug, a thermistor to control temperature, and to make it so I can tweet it while I'm in bed so I have a cup waiting for me. Oh, and why not a custom LCD.... Or not.
I Have been meaning to take this on for a while, just haven't had a chance.
