Well in all blunt honesty, I think the person who wrote that site is a complete moron.....And I will offer some reasons as to why I came to this conclusion:
1) He doesn't know how to write an argument, he is clearly profoundly uneducated
This is not a debate, or an article or an argument.....It is just the mere ramblings of a person who sat down to write a 'Mac Bashing' rant.....That is the key objective and hence from that point forward, there is no argument, there is only subjective, biased.....rubbish?
2) A lot of the things he says are just un true.....For example, yes OS X may be based upon FreeBSD, but it is modified and amended by Apple to suit their computers, anyone who has used OS X will have clearly noticed the distinct modifications to order to form the OS Core suitable for Macs. In other words, they used a 'core'.....Well, lots of OS's do that? Secondly, I have no idea what this person does to Macs to make them 'Crash a lot', because my Macs have NEVER crashed. That said my PCs very rarely crash too these days, but all the same his point is null and void. Further evidence that this person is only interested in forming a biased and un-academic rant. I could go on, but I won't.
3) He paid for a domain, hosting and made a website in order to fulfill one core objective: getting angry at Apple.......This is quite worrying, sad and leads me to ponder whether or not this individual was hit on the head by an Apple Computer at a young age, or was viciously assaulted by an Apple employee....as he seems rather upset and that is a long way to go to settle one's emotions. In my humble opinion, I suggest he gets out more.
So to conclude, I hope a crazed Apple fanatic locks him in a room with a Steve Jobs blow up doll and 20 iMacs for the rest of his life
