Bryant at AeroXperience is back with part 4 of this 5 part series on the pillars of Windows 7:

This particular pillar focuses less on personalization and more on delivering your media to you quickly, efficiently, and vibrantly.

Most of the material in this pillar is covered by the ehome labs, which means most of the material covered here will be fairly vague.

Pillar Four: Optimized for Entertainment
