My friend has the voyager and I was playing with it today and I didn't really like it.
Mostly because it doesn't have a capacitive touch screen and you have to bang on it to click anything.
You can calibrate the touch on the Voyager to your touch. This one that I have now I'm not going to calibrate, because I actually like the touch setting it came with.
I don't have a problem with it un-locking in my pocket.
