I keep seeing comments here about whether-or-not consumers are using their iPhones and iPads to do word processing and spreadsheets. And I think that argument misses the point that the article was trying to make. I think the conclusion was that we don't need spreadsheets and word processors at all. There are a lot of tools out there that help you "get business done" that are not focused around typing a document or generating a chart. I get business done by using Freshbooks and Balsamiq Mock-ups.
