Bill,
The reason you get the responses is due to often (not lately) suggesting that a Mac and an Airport Extreme router is the fix to just about any data usage problem. It's not that you have a Mac. Lot's of people have Macs. My neighbor has one and it's a nice computer. I thought about buying one. I'm sure a lot of people do. No one on here is against Macs, at least not that I know of.
