I downloaded it and installed on an XP machine and it does appear to run quite quickly.
However, Apple still haven’t addressed Safari’s biggest bug – it is far too easy to close a window in accidentally Safari closing all its tabs. Both Firefox and Internet Explorer give you a warning if you try to close a window with multiple tabs open. How hard would it be for Safari to implement this feature?
Having said that, if you load the Acid2 test on IE7, Firefox and Safari for Windows, only Safari displays it correctly.
Opera also passes the Acid2 test (not displayed). However, Opera also allows you to close multi-tab windows without warning!
So as well as being fast, Safari for Windows is, along with Opera, the most standards compliant browser available. Just don’t close any multi-tab windows accidentally!
You can download the beta from the Safari download page.
Update 1: Apple’s official announcement is now up
Update 2:Â As Conall notes in the comments of this post, the multi-tab warning is working in the new Mac version of Safari.
