I ran across this plugin for IE7 the other day, and was wondering if anyone had used it yet? I have been tinkering around with it a little, and I sort of like it. It has a bunch of features like what are available for Firefox, except all rolled into one big plug-in. I have not noticed any performance hit at all. Perhaps using the adblock and flashblock is off-setting any performance issues? The save-page-to-image feature is sort of nice. I can capture screen-shots without having to open another application; I have never really used mouse gestures before (in spite of the fact that there is a Firefox plug-in for it), but I sort of like that feature also. Super Drag and Drop is another nice feature.http://www.ie7pro.com/
I don't know that it would entice me to change default browsers, but when I do need to use IE, it's nice to know that some of the same plug-in options are available.
