I would've just preordered if they hadn't chosen to handle the creditcard info themselves... just entering my credit card info in an HTML Form that is sent to them directly? Put Paypal inbetween and i'm happy.
Anyway, this thing will be an awesome addition to my Oculus Rift and (hopefully) Google Glass.
Thanks for making it!
PS: You should offer a cheaper "two arm" bundle designed for gaming.
