I agree. It is the lack of cohesion that is killing them in the 'cloud'. Not just in the sense that there isn't a unified UX for all their stuff (though that is also true), but they are so non-unified that they often have multiple products that do the same basic things, causing end-user confusion and quite simply too many choices. [eg. Sync, Live Mesh, SkyDrive... which is right for 'me' if I'm a non-techie and don't understand the subtle differences in each? Who knows... I'll just use Dropbox!]
(FWIW I'm a big fan of Windows Live Mesh, but I've known more than a handful of non-techies who were just confused by it when I suggested it due to the related-but-different products that pop up when they are trying to learn more about it).
This does seem to be a problem they are aware of given the unification work they've done with the products I used as an example, but they still have a very long way to go on this.
