We look at the 10 silliest tech blunders that have left companies kicking themselves over missed opportunities.
10. Microsoft saves a rotting Apple
Ten years ago Apple was in serious trouble. Mac sales were being eroded by cheaper clones from Power Computing and Radius.
The company was running low on cash, its stock was trading for around $5 (£3) a share, and it was hunting for a new CEO to replace Gil Amelio.
Then Apple received a much-needed infusion of cash - $150m - from a seemingly unlikely source: Microsoft, which also promised to continue developing its Mac Office suite.
The deal was negotiated by then-Apple advisor Steve Jobs, whom the Macworld Expo faithfuls booed at the deal's announcement. Shortly afterward, Jobs took over as Apple's 'interim' CEO. We all know what happened after that.
If Microsoft hadn't missed its opportunity to let Apple wither? We'd be struggling to play WinTunes on our WinPhones. The online music and video markets would be stagnant - or worse, controlled by Hollywood. And we'd be longing desperately for better alternatives to Windows.
