Q: I am getting my third battery and charger! What's the deal with poor quality?

My macbook is a late 2009 model.  It's always been running great, but I have some key issues that are making me question ever buying a mac again... For starters, I am purchasing my third battery and charger since owning this computer.  I am not very happy with the quality of these devices...  The battery is buldged out, and looks like it's ready to explode any day! The power supply is frayed, and exposing bare wires!  What is the deal with such poor quality products? I always thought Apple was top notch in high quality, but lately, I've been proven wrong...

Seems to me that these issues REALLY need to be addressed by Apple.  The reviews on the power supplies are ridiculous!  Numorous complaints, yet Apple has YET to do anything about it!  So my question is, what is Apple going to do about these issues?  These need to be addressed, and fixed, ASAP!  I owned a Dell laptop for 6 years, and never had an issue with the batteries I had, OR the power supply, and it cost me half the price of this macbook.
