This is exactly what they did in Canberra. We now have the new body scanners, and truly, they are usually much better and much faster, especially for those of us that used to get the full shoes off routine before. However, as I mentioned before, in my recent travelleing experience, they are still quite inconsistent about whether you have to take out lap tops and battery packs for separate scanning. It has been lap tops out on 2 out of 4 recent trips. They seem pretty standardised that iPads don't have to come out.
