Well then, the choice is clear.
Just kidding. Actually this is a near perfect spectrum of feedback. I use the pros and cons in a simple decision matrix and rank them according to what's most important to me. Color is a personal aesthetic choice, but there are practical factors to consider as well.
The final phase will be going to Sony, Borders or wherever the best display is and playing with their 600's until I'm on a first name basis with every sales and security person in the store.
Of course the choice would be easy for me if Sony hadn't dropped blue from the lineup.
