Their own separate bin? I'm interpreting this to mean, electronics in their own bin, together, is fine. One bin for each laptop, tablet, phone, etc would be madness. However, I don't think a laptop and an iPad will fit into one bin without overlapping each other. So now we are at probably four bins per person including their carry-on bag as a "bin." This is really ridiculous and will lead to even longer, more chaotic…
I generally travel with my CPAP machine also so it is quite an ordeal to get through security:
• work laptop
• personal laptop
• iPad
• CPAP machine (outside of carrying case)
• CPAP carrying case
• shoes and jacket
• backpack
• and often my carry-on luggage
