LOL! Apple Store sales-people aren't that much better.
One told me Snow Leopard could be installed on any Intel PC.
Two others told me last month Mac has no Macs available with an i7 CPU. One of them DIDN'T EVEN KNOW WHAT an i7 was!....
Sounds like the exception to the rule.
That being said, I never understood why anyone takes the word of any salesman for any company without doing any critical thinking.
For example, Apple goes out and hires a marketing firm to survey consumers to find out which mp3 player they want for Christmas. One month later, this marketing firm comes back with the findings that 98% of consumers want an iPod. Apple goes ahead and issues a press release that 98% of consumers looking for a mp3 player want an iPod, solely based on research they paid for. I think most people would be highly skeptical of those claims.
I don't know why this logic suddenly goes out the window when some salesman is trying to sell you something. Whatever it is. Windows, Mac, iPod, Zune, PS3, Xbox 360, etc.
