Itanium as a coffin nail

Nice observation at The Register:

IBM saw its Unix server sales jump 12 per cent, while Sun's rose 20 per cent. HP, by contrast, watched its high-end server sales fall 21 per cent. Fujitsu's sales fell 10 per cent, and Bull's sales fell 12 per cent.
We'll let you guess which three of the five vendors mentioned sell Itanium-based servers.
