With the emergence of more and more usable (fast, decently equipped, internal GPS antenna, reasonably priced) Windows 8 tablets I believe (and propose) that the bosses implement a section with s/w and maps for windows-based systems. I am referring to "real" windows (xp, 7, 8.x, etc), not mobile, ce etc. The convenience of carrying the essentials of your pc with you, business apps that just don't exist for the most popular portable OS's (android, iOS), even elementary ones such as MS Access, potential for installing the same real applications, has matured enough to make them an ideal on-the-road choice for everyone rather than just truckers and travelling salesmen.
I propose that this is implemented as suggested, at the "Systems" level, an alternative system to Garmin, iGo, Navigon, TomTom, etc., rather than having a Windows section in each of the others.
I am contemplating the migration to a Win8 tablet (from Android) for the reasons above (it's practically devided irrespective of viable navi solution) and have been surprised (and disappointed/frustrated at the shortage of options for navigation solutions).
