So, Internet Explorer 7 will be here, ready for rockem, sockem jet-pack action (or not) in the next few weeks. I am still not convinced that IE7 is quite safe enough to use in every day browsing, and it is not extensible, I will still stick with Firefox, but IE is coming. Microsoft will release the update via Automatic Update to Microsoft Windows users "in the next few weeks as it becomes available." Via the IEBlog, you can download IE7 RC1 to test for compatibility issues, the IE7 readiness kit, Application Compatibility Toolkit, or visit the IE development center, or read the Automatic Update announcement. Whether or not IE is ready for the world, that is still up for debate, but now at least you can be ready for it.
