Listen, I now fly a B757 and I can tell you all that I enjoyed flying the Embraer 145 at lot more. Yes its a bit smaller but a lot more advanced.
From pax comments about the Embraer, yes its small (but so are most turbo-prop, which it has replaced) but it also extremelty quiet, unless you sit in the back two rows where you can hear the engines. I used to fly SAABs and they where bl00dy noisey.
I'd love to fly a barbie het again.
