Thunderbolt has been largely theoretical so far, but with the first peripherals lining up for release in the near future, this Ars Technica article is a particularly interesting read. It claims that, at least at first, Thunderbolt peripherals won’t ship with the necessary cables, and users will have to buy Thunderbolt cables from Apple for $49 for a 2 meter cable. At some point, other manufacturers will undoubtedly start manufacturing Thunderbolt cables, which will likely drive the price down, but it’s unclear how long that will take. follow link
Opening a Folder from the Dock
Sick of the dock on Mac OS X Leopard not being able to open folders with a simple click, like sanity demands and like it used to be in Tiger? You can, of course click it, and then click again on Open in Finder, but that's twice as many clicks as it used to be. (And while you're at it, Control-click the folder, and choose both Display as Folder and View Content as List from the contextual menu. Once you have the content displaying as a list, there's an Open command right there, but that requires Control-clicking and choosing a menu item.) The closest you can get to opening a docked folder with a single click is Command-click, which opens its enclosing folder. However, if you instead put a file from the docked folder in the Dock, and Command-click that file, you'll see the folder you want. Of course, if you forget to press Command when clicking, you'll open the file, which may be even more annoying.
