Guess I look at it in terms of what's missing from what I use/require. First up, no image blocking that I can find. Second up, no support for Mozilla/Firefox extensions, which means no AdBlock (the best blocker available, beats the heck out of even image blocking), which means having to be bombarded with zillions of stupid Flash ads driving me insane!

Not sure what wgscott refers to with regards to downloading, as the only place I see to change that is in the preferences, or by control-clicking the link to do a save as..., both of which Safari has.
