iChat
Show off (without showing up)
Why wait for a darkened room and a projector to present travel photos or Keynote slides? Now you can do it all remotely, right in iChat. Put on an entire photo slideshow, click through a Keynote presentation, or play a movie — in full screen, accompanied by a video feed of you hosting — while your buddy looks on. In fact, you can show any file on your system that works with Quick Look.
Chatting for the record
Now you can save your audio and video chats for posterity with iChat recording. Before recording starts, iChat notifies your buddies and asks for their permission to record. When you’re done chatting, iChat stores your audio chats as AAC files and video chats as MPEG-4 files so you can play them in iTunes or QuickTime. Share them with colleagues, friends, and family or sync them to your iPod and play them on the go.
Instant video chats and IM
Visit home anytime and never miss a class. The built-in iSight camera on iMac, MacBook, and MacBook Pro makes it easy to video chat with up to three friends or family members at once. Of course, iChat is also a versatile instant text messaging application, supporting AIM and Jabber Instant Messenger clients. Icons and thought bubbles make it fun to see who’s saying what, and you can transmit any kind of file — from a web address to a photo — by simply dragging it into your chat. Pictures display right in the message window, web links open with a click. In short, iChat is the best way to IM.
