floobie said:- Overpriced: Depends on what you want. You will always be able to build a computer with comparable hardware (ie. CPU, RAM, GPU, etc...) for less money than you'll be able to get from Apple. No argument there. What differentiates Apple products is build quality. Arguably not as big of a deal for a desktop. But, a huge deal for a laptop. A well built laptop will always cost a few hundred bucks more. Look at a Lenovo Thinkpad. No argument there. But, to say Macs are overpriced isn't really accurate. They're overpriced if you don't want what they offer. But, they're worth every penny if you do.
He zips through everything at lightning speed, making heavy use of all the OS' unique features. So, if I had to guess, the interface is probably the main appeal to such users at this point. Not to say that Windows can't handle the same applications admirably.
It doesn't depend on what you want at all. The starting Mac Pro is worse than my current PC (and generic store-bought PC equivalents), at twice the price.
Nor is the build quality anything special. It's standard stuff - Hardly some high-end enthusiast wiring or superb airflow management.
Granted, on the laptop side of things, Macbooks are far tougher than the competition due to the casing, but the parts aren't anything special there either. That said, the Macbooks are far greater value for money than anything else Apple sells.
In regards to your friend...That's nothing beyond being used to that environment. Aside from being able to mark folders and files easier, OSX offers no better UI or tools/shortcuts than Windows.
