Speed Download for Mac was one of my favorite software programs on the internet until it was replaced by Yazsoft. My problems with Speed Download were more than just the interface. Speed Download for Mac felt clunky, and had some major performance issues. There were some major crashes that happened while using Speed Download for Mac. I would have liked to have seen an update with newer versions, but like anything else, time will tell.
My other major gripe with Speed Download for Mac was its use of iWork icons in the default menu. My wife and I use a number of different iWork apps, including lots of third party productivity tools. The icons in Speed Download for Mac, while much improved over previous versions, still left something to be desired. We'll get to that in a minute.
