I went ahead and upgraded my MacBook to Yosemite today. As is usual with recent OS X upgrades, it went smoothly and I didn’t have any problems. My MacBook seems slower, but that may be due to some post-install stuff that’s running in the background or something like that. I’m going to give it some time, and see what happens.
I’m not seeing anything in Yosemite at this point that I’m at all excited about. But I’m also not seeing anything that bugs me too much either, except for the way they screwed around with iTunes yet again.
I just bought the two new Yosemite books from Take Control, and I’m hoping that I’ll learn something from them. Oh, and I should really read John Siracusa’s review. I’m assuming that there will be some useful stuff in there.
