It's quite simple really.
Apple had 2010 all to itself really on the Tablet front and made a load of money from being the No.1 out there.
Android tablets. Proper ones, are now only one hill top away and if Apple doe snot move fast and decisive in a big way, Android will be right up there, and Apple will find itself in a direct battle in the market against a dozen or more tablets, all looking very nice, and many boating specs around the same as Apple or even better and they will steal sales.
If Apple want to avoid this and totally blow all their advantage, they cannot do the typical Apple thing of a little tweak each year.
It would almost be criminal of Apple to throw away the giant advantage then have today, so that in 2 years time, they are just 1 of many on the shelves and being outsold.
Apple cannot rely just on blind brand loyalty to stay No.1
I hope they are brave enough, and not greedy NOW, to understand they need to perhaps take less profit short term to totally nail the competition and kill them in their tracks by blowing them away with the iPad2.
