For Windows enthusiasts, Windows Vista Beta 1 is a much-needed demonstration that Microsoft can still churn out valuable Windows releases, after years of doubt.

Part 1: Look and feel, desktop search, data visualization and organization
Part 2: Security, networking, power management
Part 3: Printing, unique Vista features, unique Tiger features (Coming soon)
