I'm a Canadian with GE. I live in Vancouver. Last weekend I travelled to the USA with my wife - She doesn't have GE so we used the 'new' CBP automated passport control kiosks.

From my perspective, the experience was almost identical to GE (absent the fingerprints) -

- Scan passports
- Take picture
- Answer some questions on the kiosk
- Proceed to officer
- Answer his 'where are you going what are you doing' questions

...enter the USA.

So seems that for a Canadian, the only remaining advantage to GE (at YVR at least) is if things are busy you move to the front of the line.
