Errr... the exact same safety reasoning applies for phones. Probably more so.
Not really. Most people charge smartphones over night, while you're NOT actively using them.. So you're rarely in a situation to knock off the phone by stepping on its charging cable. Laptops on the other hand are often charged while you use them on a couch or in various random places. That's where MagSafe comes to the rescue.
However, I actually was referring to the nice feel of putting something together magnetically instead of physically. Another example of that might be the SmartCovers on new iPads.
I get what you're saying.. but still don't see a real advantage over a desktop dock (assuming that a simple charging cable isn't good enough). I also do not want to carry an inductive charger with me everywhere I go, when small charging/dock cable does just fine.
And you're not going to get rid of dock port on iDevices.. not now, not in the foreseeable future. Must have a physical port for things like syncing, HDMI video, system restore, USB audio attachments for Garage Band, etc,etc.
And since dock cable charging isn't going anywhere - Apple is not going to bother with inductive charging. They are going to leave this to Palm/HP's of the world, who desperately need "features" to differentiate from iPhone. You can take this to the bank.
