Microsoft has announced that you can test-drive a 'Platform Preview' of its Internet Explorer 9.0 browser. But how does the next-generation browser differ from IE8 and competitors such as Google Chrome, Firefox, Opera and Apple Safari?
Here's a quick primer of IE9's features, interface, availability and system requirements, and how to get the Preview of the browser.
What's new in Internet Explorer 9?
Microsoft is talking up IE's speedy performance and its much-improved support for web standards. The browser's strongest attribute is probably its adherence to HTML5, the major revision of the web's core markup language that's still under development. HTML5 will allow IE9 (and other browsers) to move beyond resource hogging browser plug-ins, such as the ubiquitous Adobe Flash, to display multimedia content online.
How does IE9's interface look?
It's too early to say. Since the Platform Preview isn't a compete browser, it's not a good indicator of IE9's final interface. However, given the growing popularity of Google Chrome, a streamlined browser with few menus to confuse users, there's hope that Microsoft will give IE9 a cleaner look and feel.
What's the IE9 Platform Preview?
The Preview is primarily a way for web developers to test their sites and see how they can implement HTML5's capabilities, Microsoft says. The company plans to release a new Preview version every eight weeks or so.
Can I use it in place of my current browser?
No. The Platform Preview isn't a fully functional browser. There's no back button, for instance, or an address bar. It opens links in your default browser, not the Preview app. In addition, some of the features may or may not appear in the shipping version of IE9, depending on feedback from Platform Preview testers.
Any particularly cool Platform Preview features?
Will the Preview run on my PC?
Yes, if you're running either Windows 7 or Vista. On Vista, however, you'll need to install Internet Explorer 8.0 (if you haven't already) and the Platform Update for Windows Vista, an OS upgrade that allows Vista to use some Windows 7 technologies. And while the IE9 Platform Preview comes only in a 32bit x86 version, it'll run on 64bit Windows 7 and Vista PCs too.
I'm running Windows XP. What about me?
Sorry, you're out of luck. The GPU-powered graphics of the IE9 Platform Preview rely on display driver enhancements first introduced in Windows Vista.
When will IE9 be ready?
It's not clear. Microsoft plans to release a beta version of IE9 after feedback from Platform Preview users indicates the technologies are ready for everyday web browsing. Again, with roughly two months between Platform Preview releases, it's a safe bet that a shipping IE9 is still months away.
What features will be in the IE9 beta?
Microsoft isn't saying. Obviously, however, the features highlighted in the Platform Preview, including support for HTML5 and other web standards, will be a cornerstone of the new release.
