Amen brother. I found instant to be uncomfortable. Sometimes DDG results were not as good as google's, but pretty good. Gabriel is also incredibly responsive and tries to solve problems quickly, every problem I've asked about has been solved or had a serious effort to try to solve. Its so "personal" that I just feel like its a search engine that cares about me, vs me being just another face in a crowd.
In any case, I still love gmail, everything else has been crap.
Also try replacing google EVERYWHERE on an android device, quite well embedded and hard to change in 100 places and still browsers use google as the search engine.
