We are all entitled to our own opinions. So I respect you there brother
But then again, Apple has its own basis. iOS is what's selling like pancakes not Macs, so if the gazillions out there are using iOS device and have gotten used to the calendar in their iOS devices. Wouldn't you think it made sense if Lion has the same calendar look and feel?
Everything was considered and weighthed when they developed Lion. They even mentioned it in the press, They were blown away with the success of iOS so they are extending it to OSX.
Quite frankly, I like the old iCal but yeah I don't expect anything in SL to stay in Lion otherwise it'll be another Cat name related to Leopard
People should start looking at this perspective and not get STUCK in the old OS.
