Both Mountain Lion and iOS announcements were expected at the annual gathering of Mac and iOS developers. The laptop update—while rumored in advance of —marks something of a departure for Apple, which has announced most of its Mac updates via press release in the last few years.

Looking at the updated MacBook Pro, however, it’s easy to see why Apple chose such a major venue for the laptop’s coming-out party. Billed as the next-generation MacBook Pro, the newly introduced model features a Retina display—the same kind of high-density display Apple previously featured on its phones and tablets. The 15.4-inch laptop sports a 2880-by-1800 resolution, offering four times the number of pixels as the previous MacBook Pro model.

The MacBook Pro with Retina display runs on a 2.3GHz quad-core i7 processor with 8GB of RAM. It features an Nvidia GeForce Gt 650M graphics processor with 1GB of VRAM, 256GB of flash storage, and up to 16GB of 1600MHz RAM. The new model costs $2199.

Apple also plans to retain its current MacBook Pro lineup, offering two 13-inch models, with a 2.5GHz dual-core Intel Core i5 processor and a 2.9GHz dual-core Intel Core i7 chip; those models cost $1199 and $1499, respectively. The 15-inch MacBook Pro configurations include a 2.3GHz quad-core Core i7 model for $1799 and a 2.6GHz quad-core Core i7 laptop for $2199.
