I guess it all depends on one's point of view. You are annoyed because your keyboard doesn't work. I'm annoyed because mine still does (work). I am hoping for something to wrong with the terrible one supplied by Acer, so that I can justify buying a good keyboard.
BTW, you should determine why your receiver (dongle) overheated. Or, just don't use that USB port.
