you can send emails, make calls, or even send text messages from the same client.
They're really trying to give Skype (and SkypeOut) a run for their money with PC-to-phone calls priced at $.02 (or less) per minute. The sound quality sample is certainly impressive and extras like phone-to-PC and voicemail capabilities seem pretty smart.
But is this overkill? I dumped Yahoo IM a long time ago in favor of a less-RAM-hogging IM client. The tie-in to Yahoo Music also offers no appeal to me. And you can bet it can't be easily disabled for people who prefer to play music through iTunes or WinAmp. There's also talk of adding *gasp* ads:
Yahoo! has made the strategic business decision to increase
monetization of Yahoo! Messenger with the introduction of an
unobtrusive ad in the client…
I believe this is just a precursor to Yahoo IPTV. They're just getting their feet wet. IM+VoIP+Music+IPTV in one app? Sure, why not.
