It’s easy to get trampled if you aren’t looking.

A few short years ago everyone had a Nokia phone. I had a tiny little GSM phone that I bought when we lived in Boston and brought when we moved to Canada. Nokia owned the mobile phone space.

Then they just seemed to stop. No radical new ideas. No answers to new phones from other manufacturers.

They lost it all.

And today everyone is talking about Microsoft buying them:

REDMOND, Washington and ESPOO, Finland – Sept. 3, 2013 – Microsoft Corporation and Nokia Corporation today announced that the Boards of Directors for both companies have decided to enter into a transaction whereby Microsoft will purchase substantially all of Nokia’s Devices & Services business, license Nokia’s patents, and license and use Nokia’s mapping services.

One day companies seem to have it all, and be impervious to competition. That can change pretty quickly if you aren’t paying attention. Or if you are paying attention but fail to admit the possibility that you might not be right this time.
