Building a mobile app. Do it step by step. Literally. There are 3 reasons.

There is very little that annoys me more than mobile applications, or worse mobile versions of a website, which are feature crippled. I'm sure it can't only be me who finds this completely infuriating.

A simple example is not being able to delete a comment on Facebook when you have second thoughts or need to correct an typo / autocorrect disaster.

I agree with this article, but nothing said here is really new insight, nor does any of it apply specifically to mobile. This is basically similar to loads of other articles written about iterating good software with the catchphrase "mobile apps" slapped on to it despite the fact that this same advice applies equally to web apps, desktop apps, etc.
