Mac Forums

I'm having difficulty choosing a macbook for myself in college next year.
What would be a better choice? I have lots of questions for all you tech people

1. What do they mean by 2.66 GHz and 2.53 GHz?

2. What would be the main difference between the 15 inch and the 17 inch? Is it just the size of the screen or does the 17 inch offer more?

3. How come the 17 inch doesn't have a SD card slot? What's an Express card?

4. Is it worth $180 to get the Intel Core i7? What does it do? Does it make the computer go faster?

5. Is there anything I should definitely get for my mac pro in the configure page? What kind of memory, hard drive, display, or other programs should I get?

6. What kind of mouse is best for a mac book pro? Should I get the Magic Mouse?

7. Overall, what is your opinion between the two? What would you get?


Thanks for your help you guys!
Also, is it necessary to get One to One membership or the AppleCare Protection Plan?
