I learned 15 years ago to not install the latest patch or upgrade until it had been 'out' 6 months. That would give the developer time to fix the bugs the patch/upgrade created.
lol.
IE7 would be no different. No one outside MS seem to know how it will be better or improved or what new features it might contain. So, when it is released, any users should be skeptical in rushing to install it.
I remember with the release of Win 98, one of MS's vp's was giving a demo on a TV media blitz. He said Win 98 was the most tested software in history and it was basically infallible. Then, the demo crashed. lol. The red-faced vp made some excuse about equipment failure.
I don't trust Gates, but it has nothing to do with his browser or OS. I've been running the same install of XP, flawlessly despite thrashing it, for a few years, with an updated antivirus, pop-up blockers and anti-spyware aps that cover malicious installs. Never really had a problem with it. I now use MS's antispyware beta and it's fantastic (bought from another company). If that's integrated into the next browser or OS, well, hey, so much the better.
I don't trust Gates because of his recent comments at Davos, in several interviews. It's clear that Gates (along with many top American business leaders - and believe me, I'm very pro-business most of the time) appear to be angling to leech from and drain the United States as it looks toward a future in China. The many comments talking down the dollar were shocking. A few would not have been surprising, but the across-the-board comments were frightening.
