biggest thingy seems to be the usb port / 4G LTE backup dongle support ,
 
it a tad faster has same more memory. 
 
 
 
if you are really worried about speed/through put and raw power , the ER7206 is still the better choice but that one doesn't offer the usb dongle 4G lte feature neither
 
 
 
IF I would need to wait for a V2 in favour of the V1 , I would only attach value to the V2 for the backup dongle needs ,
