Get ready to see some changes in the Notification Center — it's bigger and better than it was before, and it's taken the best features from its mobile sibling.
Anybody remember Windows "Longhorn" before it came out? It seems Apple took that sidebar and made it bigger, better, and a lot prettier.
Now the Notification Center — still available from its quick-access button in the top-right of the display — includes stock information and a customizable stream of information, including the weather, a world clock, and a calculator. With the ability to add other widgets, it's expected that these will be opened up to third-party developers over time.
These widgets can be adjusted, and thrown in or thrown out as the user wishes — so the user isn't stuck with the same old widgets. It also includes the typical calendar functions and other at-a-glance information to keep you updated with what's going on in your life.
