I just bought my first Android phone (samsung galaxy s6) that has wireless charging and I absolutely love it. I purchased 5 different charging mats, and I can tell you, they aren't created equal. If you get a good one, (which 4 of my 5 are) then you have no issue lining it up to charge. So much nicer than plugging in cables (which you can still do if you want to use it while charging) and very easy to use. The phone is extremely thin and no extra bulk added with the feature. I have the 6 plus too, and honestly, I don't know how i got by without wireless charging this long, it is just so convenient.
At least with a cable you can still pick up your phone and use it while its charging. On a charging pad you can't pick up your phone and use it while its charging. In my experience (with the new round Samsung charging pad) I found that It had to be placed on the pad just right and it was almost impossible to use while laying down charging since the device is bigger than the pad itself and any pressure anywhere on the pad caused the phone to rock backward or forward off the pad. Plus its extremely slow.
