Consider this sentence from Bill Gate's book (Business @ the Speed of Thought: Using a Digital Nervous System)
We had to build an internet system that was so convenient, customers got more value for their time than they did on the phone.
There are two full sentence after and before comma! Is it correct? isn't it better to be:
We had to build an internet system that was so convenient, customers getting more value for their time than they did on the phone.
To make the second one ablative absolute? how do you analyze this sentence?
