If MicroB and/or Firefox would incorporate the good features of Google Chrome, I wouldn't be interested in switching browsers. I like the Feedly add-on (and it works great on the N900) and I like the Readability add-on (it also works fine) and the add-ons from MicroB (such as Greasemonkey) don't work particularly well on MicroB (Greasemonkey totally doesn't work for me) and Firefox and Fennec are clumsy and sometimes slow.

Our privacy has been significantly eroded since 9/11 anyway; Google has a pretty good instinct for doing things that appeal to users. If my keystrokes have to go somewhere, I'd rather they went to Google than to Apple or to Microsoft. And I'm willing to surrender some privacy in exchange for the right goodies.
