Call me old-fashioned. Maybe it's just that both my smartphone and my tablet really suck (in terms of having a small display and a <i>really</i> slow CPU), but I don't really see myself trying to do actual work on a tablet/smartphone. Office applications are pretty keyboard-heavy, and with the on-screen keyboard, there is not enough space left to do anything serious (again: at least on my devices, your experience might be totally different!).<p>(I heard there are desktop systems running Android, complete with mouse and keyboard - that would be a very different story, of course!)
Not to diminish the accomplishment, but the press release title says "...make LibreOffice Beta available..." whereas it is apparently a LibreOffice <i>viewer</i>, not full-blown LibreOffice.
Awesome! Libreoffice + a sync tool like BTSync (nm the closed source for now) means we're a hopeful step away from having Google Docs as the only convenient document management solution on Android :)
