But not all people have a suitable Android 4.4.x tablet with 7"-10" screen. I was wondering if project "Android-x86" could help. After installing Android 4.4 from ISO-image on VirtualBox I must say it's a no-go :( . See my screenshots below. Project Android-x86 version of Android is not on the list of supported devices what comes to Microsoft Office for Android. Bummer.
