Yeah I'd like to know too, I have the JB+ right now and on 93 it's pretty amazing but my best Android App (GPS) numbers are 0-60 in 4.5 and 1/4 in 13.4 @ 109. I took a video of the 0-60 and confirmed that by camera, but the 1/4 I think the GPS is a bit off. Sure wish I had the $ for a vbox
I've been watching the forum for sale section checking out JB4's, $400+ is a stretch but if it's that big a difference from the JB+ I'm probably going to pull the trigger.
