@Naomi Moneypenny I don't normally comment on these things, usually it is pointless unless you are already connected to the product group in question. Wicus van den Berg, Simon Hudson and Mark Walters are bang on the money here, without information on how this search experience will practically support business scenarios - or at the very least an indication of time-scale for business tooling - it is irrelevant showing "shiny" pictures.
The Office Message center announcement (22/2 MC129617) makes painfully naïve statements and the blog looks like lipstick. I've been MS front-line, it is really easy to spot "built for demo" vs. "built for production" - any indication that there is some serious thought going into "built for production" would be appreciated.
