Why we have to go back to PC? Why can't OS X be like what it used to be in past? Stable, reliable and intuitive to use!

Yeah it did fix some bugs and it's a lot better to use compared to 10.8.2. However, the system hanging thing still remains. I have made clean installation of 10.8.3 last week, spoke with an Apple expert (who doesn't seem to have any idea on how to fix this problem). Maybe you're right that it's not a normal operation, but it's very annoying and I don't know how should I fix this..
They are not going to go back to stability like in the past.
