Apple just stole the ideas from someone else
Please remind me where Apple stole the GUI from?
This PC v Mac can go on and on like the Integrated v Modular thread or Airbus v Boeing as you mentioned. Neither is better than the other ... they are simply different and appeal to a certain customer.
Try telling Singapore Airlines they made a mistake with the 380 and should have waited for a 787 ... I think they are happy with what they have.
But the fact of the matter is for everyday living, surfing the net, playing music, etc or even editing a picture or two in Photoshop editing a video in Final Cut then a Mac might be the reliable option.
I am sure the original poster has enough information here to pick what his best for his needs.
