I've been using IE7 on a relatively slow laptop PC ever since RC1 last fall, and have not noticed any performance problems. It certainly seems as snappy as IE6 ever was, and is not noticeably different than Firefox on the same machine. I installed IE7 on my main development machine two or three months ago and have not had any compatibility issues, either.

Firefox has been my favorite for a long time prior to IE7, mostly because of tabbed browsing and several really useful extensions, especially for Web development work. I still like Firefox but find myself using IE7 as my everyday browser more and more these days. One big reason is tabbed browsing, which IE7 does pretty well and which I use all the time in both Firefox and IE7. Also, print preview in IE7 is better by far than in IE6. None of the browsers I use prints all Web pages perfectly, though, and even with IE7 I sometimes switch to Opera for a decent printout. (Opera is not perfect in this regard either, it's just that some pages print better in some browsers.)

FWIW, I find RSS capabilities largely irrelevant in any browser, since my personal preference is to use a stand-alone RSS reader (FeedDemon, in my case). However, it's useful for the browser to be RSS-aware if only for auto-discovery of feeds even if you don't subscribe via the browser, so I like that IE7 has added this capability. Also there are some interesting new things in the Windows RSS Platform, such as Simple List Extensions (SLE), and it'll be interesting to see how these evolve in IE7 and beyond.
