The typical process of hardware upgrades for digital audio players follows this model: Company A unleashes DAP 1.0, and then unleashes DAP 2.0, making DAP 1.0 obsolete. Well, it turns out Microsoft doesn’t like that mode of operation, so it issued a firmware upgrade for older Zunes along side the introduction of the Zune 2.0, upgrading all older Zunes to the capabilities of the new model.
Microsoft loves its customers unlike a certain other company, (cough – Apple – cough) which refuses to give its customers what they really want. Well, Microsoft came through in giving its customers what they really wanted, delivering wireless synching with your home computer in the older Zunes via the firmware upgrade and the Zune 2.0.
Gizmodo comments on the incident, saying that Microsoft took huge forward step in PR tactics, taking "a middling jump in hardware and turned it into a genuinely good move for loyalists."
Apart from wireless synching, the update also adds support for new codecs, podcasts, and Windows Media Center TV on the go.
Microsoft also introduced the Zune Social and added DRM-free MP3 tracks to the Zune Marketplace.
