Two Shortcuts for App Exposé

If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.

Where No Drive Has Gone Before

Send Article to a Friend

My first computer, purchased in 1979, had 8K of RAM and 8K of ROM, BASIC baked in, and no persistent storage. My first hard drive was 60 MB and cost $600 in 1989. Now you can purchase one terabyte (TB) of storage in a single 3.5-inch Hitachi hard drive mechanism for about $400.

It's easy to purchase 1 TB of storage in a single package. LaCie, for instance, has offered a 1 TB Big Disk for some time, using two 500 GB drives in one enclosure; their USB 2.0-interface version costs just $350, less than Hitachi's raw drive.

But form factor is important for devices that can accept only a single hard drive, and in the drives included in basic consumer systems. For instance, a digital video recorder like a TiVo could store 1,000 hours of programming on a terabyte drive; adding an external drive is problematic (though possible) with most DVRs.

The more storage packed into a single mechanism, the cheaper smaller units of storage become as well. Expect the release of the 1 TB drive to cause 500 GB drives to drop even further in cost (they're already closing in on $100).

With the ongoing focus on video - particularly high-definition video - and the increasing resolution of still cameras, needing a terabyte of storage doesn't seem nearly as far fetched as it used to.
