There was a lot of speculation as to what would happen with Ann Livermore once HP's purchase of EDS was complete. With that deal done, Livermore continues to manage her team, and to introduce products and services.
At Interop Las Vegas 2009, Livermore talked about HP's partnership with Microsoft to demonstrate products and services around UC and collaboration. She noted that the focus of the pairing with Microsoft was to connect employees, partners and customers while delivering unified communications solutions that offer a total cost of ownership lower than others in the market.
