"PC World ... I just never ask for advice in an area that I am more knowledgeable."
Was in there a few weeks ago wanting a flat-bed microwave (e.g. for cooking lasagne in a rectangular dish too big to rotate). They only had one small one and zillions of conventional revolving-turntable ones. The salesperson there suggested just buying a bigger revolving turntable one and using it without the turntable. Duh. Apparently she'd never heard of food poisoning from unequally cooked food. As you say, they are just there to sell you stuff and may have negligible knowledge of what they are selling or how appropriate it is for your expressed requirements.
Unfortunately, the average customer may not have the relevant knowledge to know when they are being fed bullsh*t or sales spiel. I suppose it comes down to buyer beware, but (unfortunately) not everyone is as cynical around salespeople as I am.
