Sun and Google?

This one has me wondering. I think they plan to split the cost of development and that is what the partnership is really about. Sun can't do it without the big money and Google has the big money but not enough talent on hand to propel their projects forward at the desired rate. Two very different companies with very different needs. I can understand Google wanting good server hardware it only makes sense but why does Sun even care about googol beyond the sales relationship? What does OpenOffice and StarOffice have that Google would even be remotely interested in? People may like the functions of the Google toolbar but they won't like the intrusive nature of another office suite no matter how functional, to be installed on their computers in a piggyback way. I think the amount of people downloading the toolbar will fall with the move and in the long run it will hurt both companies. I've been wrong before but on this one I'm pretty sure.
