The feature list is comprehensive: Use Yahoo Go to manage photos, search Yahoo videos, watch stored movies on your hard drive, listen to music and manage television shows via a full DVR (like Tivo or Microsoft Media Center). Yahoo Go is only available for Windows machines.
It’s going to be hard for Yahoo Go to compete with Microsoft’s Media Center for the simple reason that it won’t be built into millions of PCs like Media Center is. But at least they are now in the game. More from GigaOm (my head still hurts from drinking scotch with you last night, Om) and Dave Zatz.
