I think the -700 is a significant improvement in both handling and flexibility compared to the -300. Although we don't operate it on very long sectors (yet)it has the weight and thrust capability to do so, and the flight deck in terms of the EFIS is a quantum leap.It's a pity that some type of EICAS was not incoprporated into the system, also push buttons on the overhead like the 767 would have helped as well. Unfortnately, there is no denying the reasons why these features were not installed. The predictive windshear and Enhanced GPWS are excellent new geatures also.
