What has happened to Apple?

Okay. I've been an Apple fan since the beginning, but things are falling apart... Mavericks is buggy. Mac Mail hangs ALL OF THE TIME.. I've never had to force quit as much as I do now. My iPhone/iPad is buggy and iTunes is just going nuts. If I go to a song, it just starts flipping out and moving to other songs (and it never did that before)... Sometimes when I end a call, it never ends until I shut down my iPhone and restart it... And don't get me started on final CutPro X. I really hope that Apple follows Steve Job's ideas, because since his passing, Apple has not been as reliable and as awesome as it used to be.. Please fix... I'm using the latest MBP Retina and newest iMac and iPhone. (I liked the way it was. I wish I could downgrade)... Thanks..
