It's probably a safe bet that Microsoft will continue to invest in SkyDrive, particularly in terms of Windows 8 integration. Office 2013, for example, will save files to SkyDrive as a default setting. One feature I half-hoped to see already, but didn't, was optional Skype integration. In general, the current list of SkyDrive apps is a tad thin. It is interesting to note that there is a messaging module that features Facebook integration (pictured); it seems like Skype would be a natural fit here, given that Microsoft owns the platform.
I was generally impressed by my early experiences with SkyDrive and am going to continue using it beyond this initial test. That's saying something, because it would be very easy to walk away at this point. I am mildly concerned that future improvements and functionality, particularly on the apps front, will be laser-focused on Windows 8 and related applications, and won't offer much benefit for Windows 7 users. That would be a problem because a lot of the filesharing and storage platforms start to blend together for garden-variety use cases, so the apps and integration points help as differentiators. If I'm wrong and Microsoft doesn't ignore Windows 7 users on this front, SkyDrive might become I service I regularly rely on.
