I just got automatic upgrade for Safari to version 4.
What a nice browser. It looks better, feels better, renders faster, has a really cool 3d preview page for top sites and very good interface, small and non-distracting buttons.
I am using Firefox, IE and Safari at the same time and prefer it over the other 2.
Truly, it's quite a nice browser. Yet currently I'll be more around the firefox since some of sites need plugins to view them, and they don't exist for safari. I don't know if IE works fine for you, but for me it takes like 20-40 seconds to open, which is annoying when you accidentally open a random page with it.
I switched to other account since marth 2010. Guess which.
