I use Xeons and soon will be using Itaniums on the job. They are the only choice for high end server computing outside of Alpha and Sun of course. They have the cache and other options that server apps require. The P4 has advantages for certain functions but overall when you compare price, function and speed AMD is a fantastic choice for personal computing.
On a side note I have a 16 processor (700 MHz 2meg cache Xeons) Windows 2000 Advanced Server/SQL 2000 Enterprise Active/Active cluster with 8 gig of ram and 4 shelves of 36 gig Ultra 3 SCSI drives attached via gigabit fiber channel that I designed, built and manage. There are some things that AMD may never do as well as Intel but not many people have this setup at home. AMD is the logical choice in home computing right now.
