I have never quite understood why Speed Download has run to four versions, as I never had any trouble with it an any manifestation. I have always assumed that any changes were made only to conform to changes in the Mac OS.

What do I like? SD remains invisible until it is time to download. It opens itself, snags the download, downloads it as quickly as your connection to the Internet will allow, TELLS YOU WHAT IT IS DOING WHILE IT IS DOING IT, gives you an excellent idea of how long it will take, puts the download where you have told it to, expands and opens the downloaded file, and disappears. It works equally well in all of my browsers--IE for Mac, Firefox, Safari, Mozilla, OmniWeb and Camino. It works equally well on my old G3 B&W 400 MHz running OS X 10.4.10, and my old iMac G5 PPC 1.8 GHz running OS X 10.4.10.

Also, if a download is interrupted--by, for example, a power outage, a server failure, connection--when power or server or connection is restored, it goes back to work FROM THE PLACE IT WAS INTERRUPTED to complete the download. If you are still using a 56 K modem, you NEED THIS APPLICATION! Now that I have a high-speed Internet connection, I am not sure I need it so much: but I admire it so much, I have purchased two copies of the current version, although I got no discount on the second one . . . .
