Guys, I'm surprised Macrumors and others seem to be missing the clear intent behind Magsafe: the main issue stems from flat inductive chargers being annoying with coils and alignment, many times an iphone won't charge due to misalignment.
Apple tried to solve this with Airpower but failed, in part because having 24 coils was just insane. And no one was going to pay $300 for a charging base that had NASA-grade engineering inside (no joke, look at the patents behind it).
So a simple solution is magnets, you can now place your iPhone on a flat surface and easily know when it 'clicks' in place. Same concept as the Apple Watch. This is the main intent behind Magsafe.
Now having said that, let me point out the following:
1. Wallet magnet is an afterthought, and as such it's a poor idea, as already demonstrated it detaches too easily.
2. Magsafe is a misnomer, Apple just used this name because it brings good memories to anyone familiar with the name, and it's a good marketing strategy, but there is nothing "safe" about it.
3. I'm looking forward to car mounts, I think Magsafe will work great here.
