It should show all companies logos on the mug
But then it wouldn't fit.....ha
IMO, It all comes across as pathetic on Microsoft's part. Brands are supposed to have personalities. Microsoft is not the biggest company it once was -- especially when the adversary you're talking about is Google -- but pushing out a raft of gag products that fall short of actually being funny is beneath them. At best, it's a distraction from what the company should be doing, working on good software, services, and hardware products. At worst, it reeks of desperation.
