As Rob points out in his blog, there is a good article this week in the latest PC Magazine on "Why You Want Vista Now!" It's an excellent overview of the new OS and the benefits it will bring. As a resource, I've found that PC Magazine is well worth the subscription (and I often enjoy Dvorak's columns).
I also like the new layout of the "First Looks" section (where the print magazine provides a quick overview of new products), and this month's Build It column (also online) on how to quiet your PC. A good reference for people who are looking to move a PC into the living room (as a home theatre PC or HTPC) or frankly to make for a quiet office.
