IBM's offer for Sun stalls - Yahoo and Microsoft all over again?

As details of the broken down talks between IBM (IBM) and Sun Microsystems (JAVA) come trickling out, one can't help but wonder if Sun is making the same mistake Yahoo made by rejecting Microsoft's takeover offer last year.

Just 14 months ago, Yahoo turned down a rich $44 billion from Microsoft (MSFT), which led to co-founder Jerry Yang getting booted from his CEO role late last year. Could the same fate await Sun CEO Jonathan Schwartz after spurning IBM's more-than-generous $7 billion offer over the weekend?
