I think the buyout will ultimately be a good thing. Java will continue to be developed and I get the feeling Oracle will use MySQL as a lower priced solution, probably paired either with Solaris or Linux, as compared to Oracle Database server. I just think they can coexist as product lines.
I equivocate, therefore I might be.
My Linux/Unix Boxes:
