Ed,
If you think *you* have problems with computer salespeople, try being a 50+ yr old female < grin >. I was looking at laptops at CompUSA and Frys recently, trying out different configurations, and every salesman assumed I wanted something with email and internet browsing only. The first 3 tried to convince me to get an IMac, and NONE would even discuss operating systems. I mentioned "SQL-Server" and "WindowsNT" and was informed that "Microsoft Office will give you everything you need".
Then there was the salesWOMAN who asked if the computer was for my grandchildren....
Needless to say, the actual cash went to an on-line company.
