Men also make ridiculous generalizations.
I grant that more women shop for the sake of it. And I wouldn't personally dream of browsing round a clothes shop to see if something appeals to me. But plenty of men do.
And one thing I DO like doing, which my wife would never consider doing, is browsing round a techy-type shop (like Maplin or PC World), or a charity shop, or a bookshop, or - yes! - a CD/DVD shop, to see what might appeal to me. So yes, I also mourn the demise of HMV.
The shops have to become more tech-savvy, nonetheless. For example, if I go into Waterstones and see a book I like, I'd still prefer to read it on my e-reader - particularly a hardback. But if Waterstones were to include a voucher in the book which allowed me to download a copy of the e-book for free - or even for, say, 99p) - I might well buy the book in any case.
