this august has been a month of upheavals for the IT industry. hp had posted weak revenue earnings (again!) for the last quarter, in addition to announcements that it would close down its tablet and smartphones businesses and was considering the divestiture (or spin-off) of its pc business division. less than a week later, steve jobs resigned as ceo of apple, but had been appointed as chairman of the board. these major news from hp and apple may seem disjointed, but there's one common lesson we can learn from these two IT giants.
