The Macbook Pro is clearly the flagship line in this Mac laptop computer comparison. Unlike the Macbook, which is only available as a 13 inch laptop, the Macbook is avaialble in 13, 15 and 17 inch sizes. They cost $1199, $1799 and $2299 respectively.
First, let's talk just a bit more about the Mac laptop comparison between the Macbook and 13 inch Macbook Pro. The Pro is $200 more, and for that you gain quite a few features - more ports, a backlit keyboard, a sexy aluminum body and two extra gigabytes of RAM. However, all the other hardware is the same. Are those features worth $200? Yes - but only if you need them. If you don't, they're not.
The Macbook Pro 15 inch and 17 inch, on the other had, have no Mac laptop computers for comparison. They're in a class of their own. The 15 inch Macbook Pro is Apple's most mainstream laptop. It also has upgraded hardware compared to the 13 inch Macbook Pro. The hard drive is larger, the processor is faster and the GPU is also quicker. The 15 inch Macbook is expensive compared to the 13 inch model, but some people need that power.
The 17 inch Macbook Pro's value is less obvious, however. It is $500 more than the 15 inch Macbook Pro, but has no significant hardware advantages. When compared to the most expensive 15 inch Macbook Pro, which is $2199, the base 17 inch model is both more expensive and slower.
Verdict: The Macbook Pro laptops are great products, but the one you should purchase depends entirely on your needs.
