Safari 4 beta : first impression
We've spent a little bit of time checking out Safari 4 Beta on both Windows and Mac, and here's what we like (and don't like) so far:
Windows On Windows, if you've never used Safari but used Chrome or Opera, it'll actually feel a lot like that, with the overhead tabs, Speed Dial, and even a few Chrome icons. After years of shunning standard Windows UI elements—which seemed especially dicky in a way, given how anal Apple can be about standardized UI themselves—Apple is actually playing nice. It's got the usual minimize, maximize and exit buttons, standard fonts and even real Windows shortcuts like Ctrl+Tab to cycle through tabs, so it actually mostly feels like it belongs on Windows now. Well, except for placing the X to kill tabs on the left side, which is annoying 'cause on Windows it should be on the right. I'm still not quite sure how I feel about the pitch black look of the top tabs in Windows when the window is maximized if your default window color is one of the darker shades—yeah, it matches, but I think Chrome's approach, with blue tabs set down a little bit that are easy to distinguish, works a little better. Overall, I think I prefer the tabs on top, at least in Windows. What I love for sure is that there's an actual arrow on the right side which you grab to tear off the tab into a new window—which results in a cool little pop-out
Mac Despite its Windows improvements, the new UI does look much better on OS X overall—the new tabs on top look works really well, I think, though its break with a more standard OS X layout might vastly annoy some people. Also History and Cover Flow look and feel more natural on Mac too. Another Mac perk: Multitouch zooming, which lets you manipulate the new full-page zoom with iPhone pinch gestures. It's not silky smooth, but definitely slick—it's actually a lot like browsing a page on the iPhone, especially if you're using two-finger scroll to pan and stuff. Speed difference between Safari 4 and Firefox is a bit more noticeable in OS X. It doesn't kill Firefox, but there's definitely a difference. Cover Flow runs more smoothly, from what I'm seeing, without the jerkiness I got on Windows sometimes, though full history search isn't any quicker—but that's still plenty fast. It does use resources more efficiently in OS X than in Windows: Those same 14 tabs only ate about 230MB of memory. While it's hard to speak to stability yet and whether or not you should use it as your main browser, it seems okay so far and the new features and UI make it worth grabbing, even if you wanna hang on to a more stable build of Safari or Firefox in the meantime.
