It's very simple folks...
If you have some money and need a new computer, shop around. If you think that Macbook Pro's are too expensive but that a Macbook might do, go to an Apple store and test it for yourself.
Do you automatically by the car that has the biggest engine? Of course not. Apply the same thinking to buying your computer which is:
- Does it do what I want?
- Is it fast enough?
- If its a laptop, is the battery life long enough?
- Will I get good, fast, accurate customer support? (With only 1 phone call?)
- If its a laptop, is it light enough? Does it feel solid enough?
- Etc etc etc...
If you take everything above into account, no matter what computer you buy, it will be "The right one for you".
Personally, I don't edit video on my Macbook so I don't need a bazillion core cpu. I'm happy with the 9 second boot-up speed
I use it for email and web surfing and site design and customer support and Skype, music, movies, FTP, etc. It's more than fast enough and the batteries last over 9 hours of real world use. It's the "right computer for me".
