That might be true in the future, but speaking from the present, this is how it is.
For perspective, I have written Android apps using AIDE on a Nexus 7 and Nexus 5. I also manipulate docs and spreadsheets using google's systems (which are adequate for making quick edits, but not something i would sit down and write with for an extended amount of time).
I think that the AIDE IDE is a great piece of work! Admittedly, I have only created fairly trivial apps using the template projects, but it is amazing to be able to compile Java code and create a bundled Android application on my Android phone.
It seems to bother my son a great deal that I have always used Android phones and never an iPhone. It is the availability of things like AIDE that make an Android phone also functional as a "real computer."
