Great feedback, marred by a pointless "Iron Man reference was juvenile" comment. I for one found the example spreadsheet entertaining, and it made the product more appealing to me as a result.
Well as someone in their target group (or maybe not, as someone above remarked, I don't know) I did find it juvenile. What's wrong with saying that? Or do I need to carefully construct everything I say with 'this is just my opinion' etc - this is just an off the cuff report from a first time user to help these guys out, I don't think it's reasonable to expect I'm going to be all touchy feely.
