Sounds like the iPad Pro DOESN'T use Lightning! Hurray! 100% of the Lightning devices I've used have that port die. I love the Surface line, but for a couple of reasons I like the iPad better as an eReader, BUT I wasn't buying another one if it used Lightning (I'm still on an iPad 2 for that reason...)
Weight's awesome, same as a good 10" tablet but with basically a 13" screen, is actually impressive. I'm not one of these people who whines about weight, but 1.5lbs seems like maybe a good weight for a tablet.
