i love macs but i have to say that some of the stuff you mentioned is just bull. OSX being the most advanced operating system out there? thats the biggest fanboy statement someone could say.
number one in hardware? i suppose you meant the build of it. i personally dont like the aluminum that they are using on MBP because they get dented way too easily. i do agree about the build quality of older macs though. theyre are pretty though. also, have you used thinkpads before? far more durable than any mac out there and i have to say, i love the look of them. many people dont though. in terms of the specs, you can get a pc with far grater specs for a lot less. some people need that power, so would a mac be worth it to them then?
in terms of software you are right, but you put too much value to it as they're selling the ilife package at a much lower price than you stated. also, there are so much more options for free software for the mac that you cant get on a mac. there are also lost of software that you cant get on a mac that some people need. lost of 3D software is Windows only. im sure right now yorue thinking BOOTCAMP (duh), but why run windows software with bootcamp if you can run it far better on a pc with better specs??
the OS argument is somewhat true. what makes the development process for new Microsoft OS is that it has to make changes for so much more hardware and software for compatibility. OSX doesnt have to go through as much. its really a lot more work. this is the reason for the pricing. also, OXS gets new versions more regular while Windows has a 3 year cycle. If you ever tried vista and windows 7, the improvement form their predecessor was HUGE! (although vista should have been tested out more before release)
your development argument shouldn't be there at all. there are only a handful of people that buy macs for development. also, like the OS argument, theres a lot more to be done with windows development because of compatibility. also, most developers who spend that much make so much more in software sales.
you could say that its Microsofts fault for wanting to be compatible with all hardware, but i think thats just being plain selfish. they're doing it so that more people have access these kinds of tools for information. sure, its all business, but its their system, and cheaper hardware that is allowing even very poor people access to the same kind of information we are through the internet.
lastly, the mac community is like a cult, not for all but for many. i mean, you're posting on a site called "macrumors.com" right? i dont think there is a "sony rumors" (there is one but its not focused on computers). or "dellrumors" "or "hprumors". you're posting about how macs are better than pc's right? by creating the thread, you just proved it. by taking the time to actually look for arguments and posting them, you just proved it.
well, thats me trying to give an unbiased opinion. i love macs and use one myself, but i cant say that they are always worth it

it depends on who is using it. it could be worth it to some, but not worth it to others. its still kinda early for me and im still a bit sleepy so i apologize for any typos or sentences that dont make sense at all

have a nice day everyone
