Google (GOOG +1%) roundup: 1) Google Wallet has lost its leader, and (reportedly at Larry Page's behest) has shelved plans for a physical credit card. Thus, Wallet will remain dependent on NFC, seen by many as its achilles heel. Meanwhile, a pending update will provide Wallet with a larger set of merchant partners. 2) Taking a page from Android, Google is adding notification support to the Chrome browser and Chrome OS. This should strengthen a developer ecosystem that has contributed to Chrome's browser share gains. 3) Peter Kafka observes few of YouTube's biggest content providers (independent or big media) are supporting paid channels at launch time.
