I love more black iPad. On white iPad immediately see fingerprints and dust.
Maybe it will have small differences.
It's often best to skip a model when thinking of upgrading. By leap frogging, you should benefit from real improvements, rather than seeing tweaks. Also, you get to use your newest piece of equipment for longer than a year or so - depending on the rate at which models are superceeded by the manufacturer.
That's my philosophy. It's also easier on the pocket IMHO.

What is the time for o charging on usb on a laptop or pc ?
A very long time. A laptop will not provide enough power.
Unless it's a Mac. USB 3.0 provides sufficient power to do the job.
