The OP is contemplating an iMac. If you're telling me he can easily upgrade his motherboard, CPU and graphics card in that computer, I will happily acknowledge an error on my part.I can replace the CPU or hard drive or motherboard if I need to improve the performance from any of these components, which I also have done. All for the fraction of the price of a new computer.My Mac is upgradable and I have. Its a Mac Pro. Its had new GFX card and an SSD boot disk to complement the existing 4 drives internally. How is that not exandable? CPU's can be swapped out for newer compatable ones too.
With a Mac, you get a complete (and usually refined) all-in-one package. But if you need more performance from it you'll have to get your credit card out and buy a new one.
The other big difference between Mac and PCs is the operating system. A Mac comes with OS X (10.7 currently). PCs usually come with Windows 7. There are a number of differences between the two systems, but to be honest I don't even notice when I switch between them anymore. Nor does my wife (who is not interested in computers in the slightest). They have different strengths and weaknesses, but ultimately achieve the same thing. One thing to note though, is that there are significantly more programs available for Windows than there are for OS X, and when Apple release new versions of OS X, you often need to purchase new versions of your software to make them compatible. Microsoft provide far better backward-compatibility with older software (something which almost holds them back). On the other hand, Aperture is only available for OS X...
All intel macs can have memory and hard disks swapped out both which will improve performance.
As for the comment about backward compatability, where did that come from? Apple have only just stopped supplying rosetta to run powerpc only apps and they stopped selling powerpc based macs in 2006. You don't have to buy them (unlike with windows and office which did require a specific version of office for vista) but you won't get all the latest features with the old versions. Worth keeping in mind too that the cost of apps on the mac tends to be less (including OS X itself) and they are easly installed and maintained if available though the app store.
