AC Adapters for PowerBook Duos may all look alike, but they're not all the same. Apple just introduced a new unit, with item number M4174LL/B, which works with the new Duo 280 and 280c models, as well as all previous models; it replaces M2781LL/A, introduced earlier this month, which also works with the new and old models. The M4174LL/A adapter works only with the Duo 210, 230, 250, and 270c models. The new item number for the adapter that works with all Duos was probably adopted in order to avoid confusion. Nice try.

Copy Disk Image as Folder
When you open a .dmg file, a disk image is mounted. You are then generally supposed to copy the contents of that disk image to your hard drive (to your Desktop, your Applications folder, or wherever). But what if you want to copy the whole disk image, including all its contents, as a folder? Hold the Option key, and drag the "proxy icon" in the title bar of the disk image window to the destination in the Finder.
