New today are three updated 13-inch models, and two 15-inch notebooks that have Intel's newest i5 and i7 Haswell processors. The entry-level 13-inch model now comes with a 2.6 Intel Core i5 chip and 8GB of memory instead of the 2.4GHz Core i5 chip, and 4GB of memory Apple was offering yesterday. Apple's also made a change on the entry-level 15-inch model, bumping the memory up to 16GB from 8GB and the processor from 2.0GHz to 2.2GHz.
