UnknowingFool writes: MS has invited journalists to an exclusive event on Monday, June 18 at 3:30 PM Pacific time. While MS has not disclosed the purpose of the event, rumors are that MS is showing off a MS designed and built Win 8 tablet. If true, what does that mean to OEM partners of MS who are making their own tablets? The last time MS made their own hardware, it abandoned former PlaysForSure partners and used their own Zune format. Music these days is mostly DRM free but that does not yet apply to other media like movies and books.
