Is this the computer for me?

What do you need the computer to do?

In my opinion, the 3.1GHz i7 processor is a waste of money. If you want to spend an extra $200 on the computer, opt for the 16GB of RAM. Otherwise, save the $200 and spend it on something more useful.

 

The RAM you listed is 8GB
The SSD (storage) you listed is 256GB.

Not sure what you are referring to with the "128GB RAM"
- 128GB of RAM can't exist in a macbook. 16GB is the max.
- If you are talking about the SSD, why would a downgrade from 256 to 128 make it "perfect?"

Agree with the above poster that the 3.1 i7 is not a particularly worthwhile upgrade.
In a 13" I would go with the 2.7/8GB/256GB configuration.

For the price you are looking at with the i7 upgrade, you could order this 15" with quad core, dedicated graphics, and 16GB/512GB from Adorama for $1800. That would be closer to the "perfect" computer imho.

You're being manipulated by a sales person. They most likely have too many of the 128GB models in the store and want to get rid of some.

 

Unless you tell us what you want to use the computer for (apps, usage etc) we can give you no advice.

 

Tell us what you're looking to do with your computer and we can then tell you if that laptop will be sufficient/overkill.
