An Office Depot manager said the following to me:
There's obviously something up with a product if there is a non working Demo on display
Then he asked me to spell "iPod"
I said "I-P-O-D"
He said, "Now spell Zune"
I said, "Z-U-N-E"
He said, "No, it's spelled "I-P-O-S"
Everyone has been saying it's similar to the iPod - I think this spelling is the only similarity.
