It eliminates(for the most part) one of the most common points of failure. The plug. The constant plugging/unplugging increases chances for breakage.

It really is nice to just drop down a phone or tablet down to charge instead of plugging it in... plus if you look at the NOKIA it uses NFC to let you drop the phone on a speaker and get both charging and music playback. Pretty cool.

This is one area my iPhone has whipped my old HTC. I went through 4 HTC's in one year due to this problem (among everything else that sucked about it)

Oh please. I could say apple detracted from the economy because it couldn't perform like December corn over the last year. I can't post a chart from my phone but look up December corn on a weekly continuation chart and then acknowledge that apple detracted from the economy because the mutual funds could have picked up December corn instead.
