I just wanted to comment on how quick viewing the notification center on my MBP is just amazing. Yes I have an iphone and I don't find myself using it that often, but quick viewing on my MBP is just amazing. I mean on the laptop it just feels better, more useful than the iPhone...I have about 5 calender appoints and 6 reminders. I probably remember most of em, but the reminders + Siri has been amazing, and now iCloud syncing and quick viewing on my laptop is just so easy. I won't say its going to increase my productivity or whatnot, just that I thought it was a great idea and that taking 5 secs every morning before or once I get to work to quick view is going to be so easy. Instead of using the Notification center on my iPhone I actually found myself going through reminders and calender apps, it just didn't feel like it belonged on my iphone...this belongs on my laptop I love the quick ability to tweet, and I am not a fan of facebook, I do get tagged in pics and posts every now and then, so it will be nice to drive by view if I have been mentioned (when it is released). Notification center is a great feature on the laptop, and I enjoy it more now than I did on my iPhone.
