Western Digital leapt into mobile access for remote storage on Tuesday by putting out mobile iOS and Android apps to connect to its MyBook Live networked hard drives. Both the free WD 2go (App Store, Android Market) and $3 WD 2go Pro (App Store, Android Market) let users get at music, photos, videos, and general files from a My Book Live at home. The move provides a way to stream content that wouldn't fit on a phone or tablet.
