"Windows 7 coming soon!!!" no date. no reason. Just churn.
Windows 7 will be out on the 22nd Oct 2009. Your local computer Shop did not try hard enough to find this out?
I think the store's aim was to generate a "Cool. When?" response from clients to draw them into the store so a sales rep could schmooze more money out of the client. :) Future Shop, a large Canadian electronics retailer, does this all the time.
