Google Drive is here. On paper the Google cloud storage service compares favorably against rivals like Dropbox, SkyDrive, and Box. However, there’s one aspect of Google Drive that could force many users to shun Google in favor of the alternatives.

No, I’m not referring to the fact that Google Drive is inherently Android-centric and does not provide a mobile app client for any of the other platforms. Certainly, this is a factor for people who rely on iOS, BlackBerry, or Windows Phone mobile devices, but Google Drive can still be accessed via the Web on these platforms if necessary.
