Compared to 13inch MacBook Air with 256gb at $1300, is 13inch rMacbook Pro with 256gb worth extra $200?
They both have Haswell I5 although not sure how close/different the CPUs are.
Yes, it is very much worth it IMHO.
The US$ 1,499 13-inch MacBook Pro has 8 GB RAM, while the US$ 1,299 13-inch MacBook Air has only 4 GB. If you put an additional 4 GB in the Air, it will cost an additional US$ 100, and the price will raise to US$ 1,399.
In addition, the Pro has a Haswell 2.4 GHz dual-core Core i5, while the Air has a Haswell 1.3 GHz dual-core Core i5. Therefore, the processor in the Pro is faster than the one inside the Air.
In addition, the integrated video card in the Pro (the HD 5100) is superior to the one found in the Air (the HD 5000).
Finally, the Pro has the dazzling IPS 2560x1600 retina display, while the Air has a TN 1440x900 display, which is a low-end display these days.
Of course the Air also has some advantages. It is lighter than the Pro (the Air has 2.96 lbs while the Pro has 3.46 lbs), although not by a huge margin. In addition, it reportedly has a better battery life, due to the lower-resolution display (12 hours in the Air and 9 hours in the Pro, although these times may be different in real-world situations). However, battery life in both is breat.
All in all, I think the 13-inch retina Pro is a much better value than the 13-inch Air.
