Hmmm...I just went to google and typed in "eminently practical" (in quotes and got about 644,000 direct hits..
I used ‘bing’ and didn’t get any. Are you sure the hits were for the conjoined pair? [I.e.: I got tons of hits on bing for ‘eminently practical’, but none of them linked to that exact usage. My hits for ‘immanently practical’ yielded that exact quote in spades.]
