In the Play Store, OfficeSuite 7 Pro is ranked #47 among paid apps and games, is Editor's Choice, and rated 4.5 stars.

There is also: SoftMaker Office, Kingsoft Office, Docs To Go, Polaris Office, and Microsoft Office.

All of those, IIRC, are non-cloud-based.

So in the mobile/Android space, at least, it would appear that there is indeed a lot of interest still.
