Does anyone have any data/studies/articles/opinions on which of the below a customer/site visitor is more likely to type when provided in print or communicated verbally?

1) www.example.com/xyz
2) xyz.example.com

I thought I remembered reading an article or thread a while back but can't seem to find it.

IMO #1 is the most user friendly!
