The MacPadd is a new little fad that has come out of a Canadian Company called QMS Inc.
They quite easily offer the best matching mousepad to the Mac Desktop system out there. I purchased this product myself through a vendor in France while I was studying in school over there last year. I honestly have to say it's beautiful. The shipping from the distributor was quick and swift.
When it finally arrived, I was quite impressed. Although I had some problems with it while trying to get used to the sound the aluminum makes against rubbing the mighty mouse. I don't think it's much louder, I just think that it's different, and that sound is something that you have to get used to.
