Ok, I am starting to get the product vision, mainly by reflecting on what my non-technical brother is doing with his site, Wyoming Wind. What I realize is that the close integration of the Spaces.msn.com blog service with a Windows PC's Microsoft Media Player and photo software is akin to the close integration that MAC users feel with iTunes. The integration is not experienced as "lock in" but "convenience."

What Spaces makes easy is displaying and sharing home media--tunes, photos, notes--especially for those who own Windows media-oriented PC setups, such as those increasingly promoted by HP, Gateway, Dell.

The Spaces service is just one step away from selling tunes and other audio materials--sort of "alt Podcasting" aimed at Windows machines..

And letting folks share their playlists and then buy from the central store. Much like Andrew Grumett's vision of TIVO users sharing playlists and then downloading from a central service..

The use of PC platforms this way could be a heck of a business, given that there are many more such platforms worldwide than iPods..
