Mark believes the worst product Microsoft has ever created is Windows 8.
Leo says that it is a very common opinion and it's too bad because Microsoft has "bet the farm" on Windows 8 and everyone hates it. Leo says that, like Apple, Microsoft is trying to move people into a tablet era. That's what the "Metro" interface is all about. However, there is a desktop mode within Windows 8 and Windows RT that function almost identically to Windows 7. Leo says Windows 7 is arguably the best version to date, which is too bad because we live in a "upgrade or die" paradigm that forces companies like Microsoft to constantly change their product.
