For anyone running android, I have found many of these apps to be a nice improvement and since most people will not be getting the 4.4 (kitkat) update, you can enjoy some of the 4.4 apps right now... assuming they work on your phone. I have a galaxy S3 and everything I downloaded worked fine. Playing with the new launcher, I think its a great improvement over any of the stock carrier launchers I have used. Swipe for google now and "ok google" activation could have it's uses. Hangouts can also be used for text messaging making it an easy choice for the default text messenger if you use hangouts. Enjoy.
