Don't feed the trolls.
I have the option of swapping my Vibrant for a G2 but I don't think I'm going to do it. With the bootloader issues, I won't be in any better shape with the G2.
The myTouch HD should be out around Christmas. That's got my interest a lot more than the G2 now.
I would swap it just for the fact that you can get more for the G2 right now.
