Apple has been promoting new features on their upcoming upgrade to Mac OS X, dubbed Leopard. (See the features yourself at Apple's website)
The new Mac OS X desktop metaphor is the iTunes interface. If you have never used iTunes, a quick description for you: on the left you have a navigation bar with recent and frequent and convenient locations, the top has a view changer and a search box, and on the right you have the main content. If you have used iTunes and hate its interface, you can turn it off and keep the old finder interface. Spotlight can search computers nearby that are sharing files, and can even search your home computer if you have a $99-a-year .Mac subscription. The dock has flattened its background to the floor, giving the appearance of a 3D space; windows' contents reflect off the dock floor. The dock has the ability to contain stacks of icons, which act like collections of items that reveal themselves ("fan out") as though on a stack when the icon is activated. The new Finder has translucent menus, big icon previews, Cover Flow navigation, and a new feature called Quick Look.
Quick Look allows you to take a quick preview of a file's content without having to open the program that is normally used to open that file. This feature is transformational because it is pervasive: you can take a quick look into any file's content without having to open its native program, at any time from any Finder window.
Apple's wisecracking copy writers bill Time Machine as a "great leap backward". What is amazing about Time Machine, is that it takes a task that is typically so tedious and impossibly frustrating and makes it effortless, automatic and even fun. You almost wish you have occasion to use it as soon as possible, just so that you can say that you've gone back in time. Plugging in an external drive and letting the OS do the rest - not even a one-click or one-button backup, no configuration, no confirmation screen. Your backup simply happens. All files. And with ZFS, really exciting (more technical) things can happen.
Spaces - for organizing your windows into working spaces, free of clutter. Yes, this has been available from other software developers, packages and vendors, on a variety of operating systems, including Mac OS X. Now a prominent software company (yes, I wrote software company, and yes I am referring to Apple) makes this an integral feature of their desktop metaphor. Yes, I have seen Microsoft's Virtual Desktop software, I have used it. Apple adds its signature and flair: drag and drop, animation, simplicity, and attention to it.
Mail - Now featuring stationery, notes, and to-do lists (Outlook, anyone?). Stationery now uses the media browser (also used in iWeb) and allows you to modify templates, and zoom/crop and reorder images. It is smarter: it recognizes addresses, phone numbers, dates, and it does the 'smart' thing to do: asks to create a new contact or add an address to an existing contact; asks to add an event on a date to a calendar, respectively. Mail is now also capable of displaying RSS news feeds.
iChat adds the ability to share media - pictures, movies, presentations - indeed, any file format which can use Quick Look can be displayed in a video chat. Other special effects include the same effects seen in Photo Booth, being able to change backgrounds to a picture or movie of your choosing, and other similar effects.
There are ten more top features that Apple focuses on. I will write about them on a subsequent post.
