Charlesf on Sun’s trajectory; see the full post for more insights
So what happens next? At one point today, if you netted out cash, Sun as a business was worth about $4 million (less with committed downsizing costs). Maybe Fujitsu gets interested again as they unwind their Siemens partnership. They would probably pay $4 million for SPARC. But with the cash position, anyone could come along and cherry pick a very small asset out of Sun and walk away from the rest. Maybe the econalypse (I am still looking for a good name for the "current economic situation" -- leave any ideas in the comments) precludes this, but current Sun situation isn't sustainable.
I still think a joint HP/Oracle deal would optimize what remains of Sun (e.g., HP takes Sun’s hardware and services, and Oracle takes Sun’s software and related patents)
