I tried to do the same after upgrading my Linux Mint but I couldn't resist more than a couple of days, maybe I'm too used to Google UI..

but I agree with some of the comments, sometimes I know I should search something on Amazon, Wikipedia, iMDB, Tripadvisor etc.. and I just use Google to go there (because typically if you search a movie iMDB is one of the first results, if you search "hotel xyz review" you got Tripadvisor etc..)
