As it turns out those rumors were indeed true after all, as Microsoft revealed today that Windows 8 would indeed be getting their very own app store. A team is apparently working on the store now although as to what it will be bringing to the table remains to be seen.
Considering that Mac users can buy and download iWork from the Mac App Store, it wouldn’t be a stretch to imagine that Microsoft users will be able to do the same for MS Office. Perhaps approved/authorized apps may cut down on issues such as viruses and malware.
