'Native' look and native font rendering on Windows Vista / XP

You can specify multiple video sources with . Thus, annoyingly, you can encode OGG and H.264 files and the browser will pick the right thing.

Leading the way with innovation.

Who cares as long as it’s in our laps. Let’s not forget that Safari was the first publicly shipping browser to render Acid 2, and now the first publicly shipping browser to render Acid 3. Apple invented the canvas tag and were key in CSS animation and transforms. There’s tons of innovation here, don’t doubt it.

Ah, well said. Safari 4 beta is a for-public-consumption release, offered by default. Opera 10 isn’t.

IE8 does not pass Acid 3! It doesn’t support SVG for starters. Secondly, this claim was made by Apple on their features page. I’m with them, in that Safari 4 is a browser for public use, offered by default on the website. Opera 10 is not, you have to specifically go to opera.com/next to get it. Opera may have rendered Acid 3 first in the labs, but it needs to be in people’s laps, and Safari has done that better.

IE8 does not pass Acid 3!

Fact is Opera is still publicly downloadable, despite whatever semantics Apple's BS crew spew out on their web site.

There is no ability to reorder the tabs

dragging the only tab out of a window does not destroy the window, and the animation, while nice, is way too slow.

That being said, this is an awesome release. I would use it over firefox any day, but I will keep chrome for my day to day browsing for now

Til then, we have to gather as webmasters and block users of versions of IE that don't comply with web standards.

"IE8 does not pass Acid 3!

I'm not a big Microsoft fan, but to their credit, I don't recall any cases where they've tried to use patents to push people around. They, and other large companies have no choice but to file a patent every time they take a crap in order to fend off patent trolls.

If MPEG4/h264 wasn't patent riddled to high heaven, we would have had a stadardised video format long ago. Thanks to the infinate wisdom of politicians and their enablers we now have a industry fragmented along political lines and each organisation or company thinking its beneficial to screw other companies in the process.

There are solutions out there, too bad the concern by organisations is short term profit at the expense of long term innovation and new business opportunities.

Agreed. Totally.

Patents, inter-operability and access-for-all are concepts that don't really mix at all well. Open unencumbered standards are far, far better for everybody.

Vorbis for music, speex for speech, and FLAC when quality is required but compression is not, and Theora for "videolets" and Dirac for higher-quality video would seem to be the best options for avoiding all kinds of patent issues.

If you have a custom theme in Windows, Safari does try hard to fit in, but seems to make mistakes with the height of the titlebar http://bayimg.com/HANCmaabM It handled my theme not to shabbily, all things considered. The weirdest thing is having no menu in Windows.

Uhm, Opera 10 Alpha 1 beat Safari to the punch. Unless you're saying the beta release is a general release.

Actually both IE8 and Opera 9.6 / 10 (or whatever the lastest version number will be) betas scored 100% on Acid3.
Given this is no more than a beta and the fact that Opera's latest beta is publically downloadable (I believe - though unsure - the same is true with IE8) - I really don't see any truth in your / Safari's claim.

As for inventing tags - I get nervous when browsers create tags outside of w3c's control.

Another reason is that Safari has lacked really basic things like session-save and crash protection. To get that, you have to buy Saft, which becomes a bit of a pain every time Safari gets updated. Did they fix that yet?

No need to exclude IE, just to exclude those versions of IE that do not comply with standards (IE6 and below in particular).

Pff. Tried out Safari 4 Beta and it scored only 98/100 on Acid3 (@ Windows 7 Beta 1). Had a Mac-using pal check it out too and he got the same results.

What good is HTML5 audio/video support without mandatory Ogg? It seems that (thanks to Nokia) we'll see the the same old "each browser does it its own way". Firefox will go with Ogg, IE will pretty surely go with WMV/WMA, and Apple, it seems, will go with MPEG4. The obvious outcome is that Flash/FLV will continue being used because it's the common denominator. And that sucks...

"Another impressive feature that Web application developers will be able to take advantage of in Firefox 3.1 is support for worker threads, which provide support for concurrent execution in JavaScript. Worker threads will make it possible to perform complex computations in the background, so that the browser and Web application don't hang or become unresponsive.

The HTML 5 video element will also arrive in Firefox 3.1. This will allow video content to be embedded directly in Web pages, controlled with JavaScript, and manipulated through the DOM. It's a major step forward for rich media content on the Web. Firefox 3.1 will ship with built-in support for the Ogg Vorbis and Theora formatsâ€"open audio and video codecs that are believed to be unencumbered by patents. The actual codec implementations are integrated directly into the browser itself, so content in those formats will be playable without requiring any external components or plugins.

Blizzard says that Mozilla aims to encourage an explosion of creativity around video that will mirror the kind of uninhibited innovation that has flourished in the Web's inclusive standards-base ecosystem. Mozilla is actively contributing funding to Ogg development efforts to help accelerate the process. He says that Theora, which is used by Wikipedia, has the potential to achieve quality comparable to MPEG4. High definition video, however, will require the Dirac format, which could eventually be included in future versions of Firefox when it matures."

To illuminate the possibilities that are unlocked by these new features, Blizzard showed several technical demos. One of the demos used the HTML 5 video element to display a space shuttle launch. As the video played, JavaScript code running on the page used the video time index to retrieve launch data from a JavaScript array and draw graphs that show the shuttle's speed and altitude increasing during the launch.

The most impressive demo that he showed during his presentation used JavaScript in worker threads to programmatically detect motion in a playing video. This one has to be seen to be believed

Where is the ever important option to disable JavaScript window resizing?

Opera, Firefox and even Camino seems to get that right except Apple.
