They shouldn't have killed an excellent processor (the Alpha) which already had tons of software and history and was already being used in the fastest supercomputers in the world for a product that was never (and still isn't) proven. The Itanic was never best in its class at anything.
I have to admit that as a DEC alpha user starting in 1993 (using OSF/1), and also one of the main FreeBSD/alpha port authors, the itanium being phased out fills me with joy.
