Let's start with the new iPad Air:
The new iPad Air weighs only one pound (vs. 1.33 pounds for the iPad 2), 28% lighter than the iPad 2 and 20% thinner than the iPad 2. The iPad Air will be available beginning Nov. 1 starting at $499 for the 16GB wifi only version (up to $799 for the 128GB) and $629 for the 16GB wifi and cellular version (up to $929 for the 128GB).
Now, the new iPad Mini:
The new iPad mini features a Retina Display on a 7.9-inch display. Like the new iPad Air, the iPad mini has the new A7 chip. The iPad mini will be available beginning Nov. 1 starting at $399 for the 16GB wifi only version (up to $699 for the 128GB) and $529 for the 16GB wifi and cellular version (up to $829 for the 128GB). Thus $100 cheaper across the board than the iPad Air.
Apple also announced a new Mac Pro:
I'm not going to try and say what all this does, I'm not that computer savvy, but it sounds like it's really fast and has a lot of storage. The Quad-Core Mac Pro starts at $2,999 and the 6-core starts at $3,999. Here's the link to the page on the Apple site for more info: http://www.apple.com/mac-pro/
And last but not least, updates to MacBook Pro and the OS X:
The new MacBook Pro features Retina Display and a faster processor. The 13-inch starts at $1,299 and the 15-inch at $1,999. Both are available now.
The new operating system, Mavericks, is also available now for free to all Mac users dating back to 2007. Here's the link to the page on Apple's site as I didn't have the best luck installing it: http://www.apple.com/osx/. It's a pretty large file so make sure you have enough room on your computer before you start.
