After an unusually long wait, Apple has finally released updated models of its MacBook Pro line of notebooks. The 15′ and 17′ models offer the latest Core i5 and i7 processors, though the 13′ model still uses a Core 2 Duo processor. But new processors aren’t the only improvement; Apple has also seen fit to increase the base RAM configuration to 4GB on all models and bump the hard drive and SSD options. And Apple claims battery life has been improved, with some models now going as long as 10 hours without plugging in.

The new 13′ MacBook Pro offers 2.4GHz or 2.66GHz Core 2 Duo processors and 4GB of DDR3 RAM. The lower-end model gets a 250GB 5400RPM SATA drive, while the higher-end option comes with a 320GB 5400RPM drive. A 500GB 5400RPM hard drive is a build-to-order option, as are 128GB, 256GB, and 512GB solid state drives. Both models come with NVIDIA GeForce 320M integrated graphics, an update to the 9400M that previous MacBook Pros used. Combined with a 63.5WHr lithium polymer sealed battery, Apple claims these new 13′ MacBook Pro models can run up to 10 hours on a single charge.
