With Yahoo's rejection of the unsolicited Microsoft bid last week, smiles have turned to frowns at Redmond. Microsoft is dismayed over Yahoo's statements, saying that their rejection is unfortunate. On an official statement, the software giant is claiming that it is in Yahoo's best interest to join with them rather than tough it out. It also seems that Microsoft is in talks with Yahoo shareholders, perhaps coercing them to convince Yahoo execs to sign off on the deal.

If it is Yahoo's attempt to push the bid higher, it remains unclear whether or not that will happen. And even if partnering with Microsoft is on Yahoo's best interests, that does not guarantee a general acceptance from current Yahoo customers. Sometimes integration is just a bad idea.
