    71. 83. External Commentary #1 Coolest technology demoed at Web 2.0 “ Live Mesh… could change the way PCs and other devices interact with Internet Services and each other…” “… most ambitious step yet in transforming its personal computer business “ Despite Microsoft’s reputation of being a closed-wall company, it is adopting simple protocols in its Live Mesh synchronization strategy.” “ Live Mesh represents the company Microsoft is trying to become…” Rob Enderle
    72. 84. “ Eventually, we’ll give customers instant access to any movie on any device with an Internet connection and a screen.” “More immediately, we could use this technology to reach into airports. Travelers could quickly download movies from Blockbuster kiosks to their portable media players.” Keith Morrow Chief Information Officer, Blockbuster
