What would you have us do instead, the empty cart text is 100% customizable thru the store text module as Heather mentioned. That is the default text because not everyone has cookies enabled, although it is true that almost everyone does these days or at least has a mechanism in their browser to hold temporary cookies while on the website. So, personally I do prefer heather's text that she changed it out with.
We are open to suggestions but just feel that all needed levels of customization are there, you can even personalize the message with site merges and customer merges and such.
