If you want to only use the software that comes with the computer and never want to try anything new, don't care about games, don't want ever to upgrade your computer instead of buying a new one, and don't mind that you are getting less performance for your money, and want to pay a huge premium, buy a Mac.
If you want to have a MP3/portable media player that requires proprietary software installed on a computer instead of showing up as a USB memory, has limited codec support compared to competitors, and you are not going to DL music or videos outside iTunes like ever, don't want to change the battery yourself, and you want to pay a huge premium, buy an iPod.
If you want a phone that only runs software Steve Jobs considers appropriate for religious fundamentalists (ie. farting simulator is OK, models in swimsuits are not), has less features than competitors, which may not work correctly, don't want to change the battery yourself, and you want to pay a huge premium, buy an iPhone.
If you buy anything by Apple, you are essentially buying stylish design (a matter of taste, though) and ease of use while giving up the full range of use and technical qualities of the end product, all the while paying way above reasonable prices. Also, Apple seems to be moving towards "auto manufacturer" type of business model, in that they charge you even more for the associated services than they do for the product itself, eg. the battery needs to be changed in the official service and in the worst case they simply send you a new iGadget instead (hopefully, you had a backup copy of your precious data!).
If you want Apple iWhatEver for the looks, or are buying it either for your children or technically challenged but wealthy grandparents, go for it. If you want iWhatEver it for the features or consider value for money at all, well...
