So let's get this straight:
1. Microsoft is well known for the security issues and slowness of their ACTUAL browser.
2. They decide to prove that it's hard to build a secure and fast browser.
3. They give out a press release claiming that they have built the secure browser, and it's indeed slow -- but nobody can see it to test its security or determine how fast it is.
4. They name this SLOW but SECURE project "Gazelle" (and not, say, "Rhino") !?
Why do I tend to think it _actually_ went something like this:
1. MS Engineer says "Hey, I have this idea for a really fast browser! Let's build it -- and call it Gazelle".
2. MS Manager: Okay, but in order to get anywhere, it's got to be really secure. We've taken a big hit on that presswise. Why not do some virtualization thing?
3. [Browser building...]
4. Engineer: Well, it's secure, but the security features and virtualization make it kind of slow...
5. Testers: Well, we can't really say it's secure; we haven't done really serious testing of that. It takes years and lots of minds to really test for security weaknesses...
6. Manager: Yeah, but if no-one else can test it, we can use this -- at least for PR purposes...
And so a press release is born.
C'mon, Microsoft. Opera and Mozilla, and now even Apple and Google, have shown that it's possible to build a faster, more standards-compliant, more secure browser than IE7 that still manages to work with legacy sites way better than IE8. Step up.
