I too am moving away from Oracle/Sun. Yes, we still have Oracle databases in house, but all the Sun hardware is moving to a fire sale. Sad because I really like(d) Sun, but now that Oracle has made it their bastard child, I have no intention of supporting it any more. Besides, we are primarily an IBM shop (p570s/p750s) and a smattering of Linux/Microsoft support systems. I have really come to appreciate the robustness and power of the pSeries hardware.
I met with Oracle a couple of times and always walked away shaking my head and thinking to myself, "These guys just aren't serious about supporting Sun." They talked a good talk, but it was like their heart wasn't in it.
