I am generally the type of person who does not install Beta versions on my main desktop - I tend to use virtual machines to try out new software.
But when I installed the new Microsoft Internet Explorer 7 Beta 2 it found its way to my main desktop vey quickly - unlike the Microsoft Internet Explorer 7 Beta 1.
This beta is also different from the Beta 1 in scope: while that was a closed beta available to participants of the Windows Vista Beta program and MSDN subscribers, the Microsoft Internet Explorer Beta 2 is open to the technical community and developers in general. The software is available for download now.
Users will like the tabbed browsing experience, and people who lives by their RSS feeds will be happy to know that auto-discovery works well, and feeds are shown in a nice page, not unlike the ones created by Feedburner. Once showing the feed it will list on the right side of the browser all categories in that feed and allow filtering and sort actions (by feed, by date).
The Quick Tabs feature is really interesting, showing in real time multiple tabs as a tile composition in your browser.
Using the Search box is a breeze - no more entering the google.com URL in the address bar and waiting for it to load. Simply enter the search query in the appropriate field and the response will come up in the browser, quickly.
This new version now supports transparent PNG, and the Delete File option gives the user a list of things that can be cleared (cache, cookies, personal data, browsing history).
The software can be removed, but I recommend home users do not install this version. Because of its Beta status users will not have the expected support in case of something going wrong. But if you are a technical user, or a developer looking for ways to integrate RSS and AJAX to new web applications, then it is worth it.
