Chalk up another developer up for the iPhone App Watch: **Microsoft**.
Microsoft has a small team called the MacBU that develops the very
successful Office Suite for the Mac -- an office suite that until the
recent version was widely thought to be more advanced than even its
Windows counterpart and in some ways a "test bed" for features that
would eventually make it into the Windows version of Office. It may
surprise some to hear that Microsoft is looking at the iPhone for
development, but it ought not.
