I like it
I quite like the process. Much easier to fill the form in online and print it out. I got 'approved' within seconds when I filled it in for when it first started last year.
Updating it for my current trip (I am currently in the US and flying back to the UK tomorrow) was easy enough and painless.
Much easier than trying to write on a green form when you are on an airplane, remembering where you are staying a contact telephone number etc. Especially when the plane could be going through turbulance.
I think its a change for the better - but a lot of people hate change.....
