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.
It takes a special kind of person to lead! We all know this. Over the past 3 years or more, visitors to Acer Community were witness to a leader in our Top Ranked ACE member, IronFly. Recently he hit a new milestone of 1000 solutions authored. Leading the way has always been and continues to be his way. We are proud of you IronFly.
