Notes 7 & Google Search
I watched the Lotusphere 2006 keynote stream last night and found most of it to be quite boring if only because neither my customer nor myself really believe in the real-time collaboration stuff.
One thing that caught my attention however, was the upcoming integration of Notes 7 into Google Desktop Search. I've yet to use Google Desktop because of the fact that it doesn't find Notes documents. That is one feature that I'm looking forward to.
