It appears

That your example Dell Inspiron N41110 is not specific as to what application you want. If it is for Vista or ? What it comes down to is that it appears that the computer companies need to go about educating the consumer. My great grandfather would not know what his OS was either 32 or 64.. Calling into tech support or ordering online. If you as a consumer select Windows by itself and find when you receive it you needed Windows 64 bit then you have to eat that loss. It seems as if the consumer is the prey here and the manufacturer is the one collecting the profits. If all else fails get a tech or someone you know and trust that can research and help you.
