I don't think a multidimensional spreadsheet (like Lotus Improv) makes sense for a single user. Multidimensionality introduces a lot of complexity and it is only justified by very complex models. Apart from some special cases this complexity is only there when at least 5-10 people are entering the data. Web application is much easier to rollout in a corporate environment. And I don't see any drawbacks. I don't have MS Office for example and use only Google Sheet for a long time already.
