What is the Biblical basis for unitarianism? I ask this mostly in reaction to this question: What is the Biblical basis for the doctrine of the Trinity?

From what I've seen, the majority of Christians believe in Trinitarianism, but some believe in Unitarianism instead.

My understanding of Unitarianism is that, in this view of God, only the Father (as referenced by Christ) is called God. Christ is just a man, created by God and given certain powers/privileges that aren't afforded to most men.

What is the Biblical foundation for Unitarianism?

Note:

I am not asking for a debate on the truthfulness of this position, but I am looking for an argument that defends its soundness with Bible verses, preferably not limited to a single translation.

If a single translation is to be favored, I would like to know why (references to the original Greek/Hebrew used in translation if possible).  I only ask this because it doesn't seem to be a very common position to hold, so I assume there is valid evidence to support it.
In John 17:3, Jesus says:


  Now this is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent.


Here, Jesus is speaking of God as the only true God and Jesus as being sent by God, not being God incarnate.

Also, in Matthew 4:10, Jesus himself says to:


  ‘Worship the Lord your God, and serve him only.’


Other verses seem to emphasis this:  


  Mark 10:18 (NIV) 
  “Why do you call me good?” Jesus answered. “No one is good—except God alone.


Also, they take the following verse (Phillippians 2:6-8) and use this to say that Jesus had the form of God (outer appearance), but took on the form of man.  So, (ironically) while it's  central to the concept of the Trinity, it's also used in Unitarianism to show how Jesus was not God:


  Phillippians 2:6-8 (NASB) (emphasis added)
  [... Christ Jesus,] 6 who, although He existed in the form of God, did not regard equality with God a thing to be grasped, 7 but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men. 8 Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross


These concepts make people think that Jesus was not actually God and that only God the Father is actually God.
