I'm wanting to use NetHunter but I'm unsure on which device to purchase for it. Should I get the Nexus 7 as it is smaller and versatile/mobile to use with attacks like BadUSB (i.e. can hide it easier) or should I get the bigger Nexus 10 as it is faster / more powerful. I saw there was an issue posted on the Nethunter page that Nexus 7 devices (2013) have issues where it would reboot when disconnecting the USB OTG. Is that for all Nexus 7 2013 devices?

When using attacks like BadUSB it seems you have to leave the device connected so having a smaller device would seem more appropriate as it would be easier to hide. What would be your recommendations and why?
