Want to save several billion dollars, increase market share with innovation, and not be stupid in the IT arena? The answer is simple: do not buy other software companies (go all in on Open Source Everything); and if you must buy something, consult Stephen E. Arnold, CEO of Arnold IT, first. HP is a potentially great company, but it seems out of touch with reality and unable to do its homework. They are not alone — Microsoft after Ozzie, Oracle, Yahoo, Facebook, all mired in old think. The arrogance of insularity is quite stunning, across all fronts.
