Regardless of the price, the idea is good
What we need next are standards so that our desks can directly include the charging pad. One arrives at work or at a meeting and voila constant charging.
In fact, I don't really care if it adds charge, just as long as it is capable of retaining approximately the same charge for the whole day. Although adding charge would be nice too...
I am writing this the train and I would love to think that even on the train I would be able to work for a few hours without the need for cables, ( this train does have power outlets but they are above head height at the top of the window and it just isn't chic having the cables/charger hanging from above.
But knowing how standards are very seldom achieved, certainly not when there is a commercial gain to be had, I won't be keeping my hopes very high.
