I wonder which of the big old names will go first - SGI or Sun? Two companies who were the hottest properties a decade or more ago, now it's hard to see what they're for.

If you mean broken up and sold off, I would say that SGI has already done most of that already, so SGI is already gone. As far as Sun, they are still a major force in Servers and up and coming in software and storage. I really don't see the comparison.... yet. Sun still has several years to see if they can come back. They've already shown that they have multiple lives, where SGI has never shown that they can come back from oblivion.

SGI's management have been more self destructive than Amy Winehouse on a bender since the mid 1990s. In every market segment (3-D graphics, HPC, storage, software) they have repeatedly squandered strong positions whilst off chasing unicorns.
