Nice idea, nostalgic
I like the idea but I found that it didnt always work exactly as it should. On some numbers I found myself over-dialing to get the number that I wanted (it shows the number value as your rotate). I think it would be also good if the delete button didnt delete the whole number when make a mistake - just the last number entered. If these area could be improved I would use it without a doubt.
