The documents also provide more information about the Apple co-founder's drug use as a teenager as well as a previously unreported arrest in 1975 for having failed to pay a speeding ticket.

Apple overhauled its popular notebook, the MacBook Pro, with a state-of-the-art, super high-resolution screen, and updated it and the MacBook Air with the latest processing technology.

The latest MacBook Pro will be the lightest ever, weighing in at only 4.5 lbs and measuring .71 inches thick. The new Mountain Lion OS has over 100 new features including Messages, which takes iChat to an entirely new level. Users can now chat back and forth across all platforms: Mac computer, iPhone, iPad or iPod touch running iOS 5.

The new functionality extends to the iOS 6 on iPhones and iPads, for example, if you make a call on your iPhone you can continue it on your iPad. If you open a web page on your iPad, a tab will automatically appear on the screen of your iPhone.

While the new MacBook Pro and MacBook Air will be shipped out today, users will have to wait until next month for the Mountain Lion OS. However, everyone purchasing a new Mac computer is eligible for a free copy of Mountain Lion once it becomes available.

The iOS6 for iPads and iPhones will be available in the fall. But there's been no mention of a new iPhone 5, so the wait on that front continues.

3:26 p.m. ET: Three years after Michael Jackson's death, his daughter Paris Jackson says she's still coping with his loss but also dealing with grown-up problems like having a security detail and coping with bullying.

In an exclusive interview with Oprah which aired on Sunday, Paris Jackson described what childhood was like with the superstar as her dad. She didn't understand why she and her two brothers had to wear masks but now realizes that the protection allowed her to have a "normal childhood."

Paris Jackson, following in her dad's showbiz footsteps, is pursuing an acting career. She will star in the fantasy film "Lundon's Bridge and the Three Keys" due out in 2013.

11:31 a.m. EST Today on "Good Morning America", anchor Robin Roberts announced she was recently diagnosed with MDS or myelodysplastic syndrome (previously known as preleukemia) and will need a bone marrow transplant to cure the illness.

Dr. Richard Besser explains the disease HERE.

In advance of the transplant, she will receive chemotherapy. While African-American bone marrow donors are rare, Roberts is fortunate to have a sister who she describes as a "virtually perfect match."

Five years ago, Roberts also battled breast cancer and the treatment for that contributed to her current diagnosis. But she's upbeat about beating the disease and her doctors say the prognosis is good.

While receiving treatment, she will continue to anchor "Good Morning America." She also called on the prayers and support of viewers, who she credits with keeping her in good spirits and aiding her recovery during her last bout with cancer.
