Apple announced their new MacBook pro line in an event on Oct 27 – all the details can be found here: http://www.apple.com/macbook-pro/
Some of the big announcements included a brighter new display, faster graphics, new and improved speakers and keyboard, and a Force Touch trackpad. It also comes with the Touch Bar and Touch ID – Apple describes them this way:
The Touch Bar changes automatically based on what you’re doing to show you relevant tools you already know how to use — system controls like volume and brightness, interactive ways to adjust or browse through content, intelligent typing features like emoji and predictive text, and more. And for the first time, Touch ID is available on a Mac, enabling instant access to logins and fast, secure online purchases with Apple Pay.
There will be some huge changes for users with the new MacBook Pros (besides the higher price tag!) The biggest difference will be the ports – Apple has replaced the Magsafe, USB, HDMI, Thunderbolt, SD Card, and mini-display ports with 4 USB-C ports, so it’s going to require a totally different work process for most people.
There are a couple of other changes, including the removal of the 11-inch MacBook Air from the lineup. The last MacBook with an optical drive, the 13” model introduced in about 2011, is now gone, so Apple no longer sells any laptop with a place for your DVDs.
