I'd go the same route. The features a consumer needs are much lighter. I imagine the hope is that someday people will realize, "Hey wait a minute! This thing kicks Excel's ass!".

"Don't be discouraged if what you produce initially is something other people dismiss as a toy. In fact, that's a good sign. That's probably why everyone else has been overlooking the idea. The first microcomputers were dismissed as toys. And the first planes, and the first cars. At this point, when someone comes to us with something that users like but that we could envision forum trolls dismissing as a toy, it makes us especially likely to invest."
They might be better served to drop the 'Spreadsheet' moniker. It leads people to incorrect assumptions about the product and likely filters out potential users. 'Whiteboard', 'Slideshow', and 'Scrapbooking' are all terms that seem to better represent the (current) intended use case.
