No. Noone is going to buy anything because it is "integrated" with a commodity video product.
They might if it is integrated (no quotes) with the call, chat, filesharing and screenshare client that they, their clients and suppliers use (and understand) if it is integrate in some useful way or maybe if it comes with some other corporate value add (data about who employees call, chat..).
Even though it really isn't marketed that way, skype is a business tool, something people use at the office. It is used by lots of people that use Office, Media Player and IE only.
I assume by the tone of your comment that you either don't think that something everyone knows and have already been using for 5 years is particularly valuable or that you are skeptical about people continuing to buy MS for any reason. Microsoft would disagree with both of these.
If this is really where they are headed, it is just ineffective product strategy and fuzzy thinking on Microsoft's part.
They get two things:
Technology: These are technologies Microsoft already has or could develop cheaply (say, for 1% of the cost of Skype?).
Users: Yes, no one will buy Microsoft because it is integrated in "some useful way" - whatever that means. 99% of the utility of Skype is already present without an integration - and other products can also integrate with Skype or other similar technologies if there is really a value add there. There is no sustainable market advantage and no value compelling enough to affect a purchase decision. Users have all they need from Skype - making calls one click away or some light simple integration like that is not a reason to spend 8.5B on a company.
Words like "synergy," "cross-sell," "eyeballs," etc. were no doubt tossed around the MS board room with this vision in mind. Abstract synergies don't work, and integrating unrelated products doesn't work.
Ebay bought Skype because they thought lack of telephony was the reason they were getting their but kicked by Taobao in China. Nobody cared and users weren't interested. Ebay was losing because their pricing and service model were wrong for the market, but it's easier to buy companies than fix your own, so that's what they did.
People are going to continue to buy Word, Windows, and Exchange because they have a commodity video product "integrated"? I don't think so.
