I used to have PC laptops (Acer Aspire, before that, IBM Thinkpad).  They were fine.  Then I got Macbook Pro about two years ago.  Though it cost almost 50% more, I am very happy with the switch.  Mac just feels right.  

Feature by feature, spec by spec, I am sure you will find a PC laptop cheaper.  Similarly, Android phone too might be better and cheaper than iPhone.  But once you start using Apple, or rather once you take a bite of Apple, you will not want to stop using it.  There's something about the intuitive design, the robust OS, the all encompassing ecosystem, and just the sheer feeling of owning an Apple product.

Steve Jobs, you devil!
