The software giant Microsoft (NASDAQ:MSFT) is in the midst of the most monumental shift to its business in at least a generation, as it attempts to port its cash-cow software businesses into the mobile future. The results -- so far -- haven't exactly been inspiring. Its Surface tablet has failed to impress consumers, and Windows phone adoption remains tepid at best. To make matters worse, Apple and Google have both continued taking share in the burgeoning tablet and smartphone markets.
