We are talk price point here for the amount Mac charges they can not but a dedicated video card "please" Just because it is design by Mac does not always make it better. Yes OSX has a lot less issue than Win XP but do not sit here and try and tell the hardware im Mac computers also completly superior to Win machines. Becuase I will be the first to tell you are full of shit. There are 3 to 4 major manufactures of laptops and guess what they build the Mac and Win machines. I use both Mac and Win machines but I do not blindly think Mac is that much better in everything hardware and os.
You're failing to realize that when you buy a computer, you are not buying just the hardware. You're buying a solution that is meant to meet some computing need of yours. A computer without software is basically a heavy door stop. Macs may cost more than equally spec'ed Windows laptops, but for many they are cheap for their value, especially if it gets them away from the Windows spyware/adware/virus rut they are stuck in. Not only that, the ease of maintainance (drag drop adding/removal of software, etc) make it just that much more attractive. This isn't even taking into consideration the additional apps that ship with Macs, namely iLife and iWork. Sure, some similar packages will ship with PCs, but nobody will say they are equivalent unless they were severely biased against Macs. Again, this adds value. You can see where we are going with this train of thought.
Even if you were just buying hardware, specs are not all that matters, certainly not to everybody. A huge factor is build quality. I've been using laptops for years, and I have found there are only 2 laptop makers whose build quality sets them apart from the rest: Sony and Apple. All other laptop manufacturers merely produce plastic toys in comparison to the products put out by these two. Dells are the worst IMHO, as their laptops feel utterly flimsy, even their so called high end laptops. My Dell laptop broke down at least once every year(!!).
Like I've said before, I'm currently shopping for a laptop and while I don't really need a Mac, I'm seriously considering a Macbook. Why? You can surely find cheaper laptops, but here in the UK the Macbook costs £750 and all laptops in that price point (+/- £50) have similar specs to the Macbook. There are cheaper laptops, but those are not worth considering, if you've actually seen them.
