There's a USB adapter. Big difference.
USB adaptor does not work without a USB port.
USB is part of the 30 pin dock connector. Look how thick the iPad is, do you really think a full USB port is practical? Oh, mini or micro USB port ? Well you would still need an adapter to plug your thumb drive in.
No difference.
Please try to help me understand then ( am I am not being upity, just trying learn) why would apple bring out a 2nd generation ?? To only have a front and rear cam?? Seems there has been alot of talk about the display not changing enough either... I get so confused because when you would upgrade a product, don't you hope you advance it??? Why wait for a 2 then, just wondering???
Upgraded dual core CPU, upgraded ram, gyro, upgraded screen, so yes, it will be more advanced.
We will know the details when they are announced. Some people upgraded because they feel the need, brain is wired differently, gotta have a camera, always wait for 2nd gen, spouse wants one , who knows.
Why wait for gen 2? Are you one of the people that will go crazy when the newer model comes out and your neighbor gets one and you are still using a 1st gen? Do you need a camera ? Will you try to use the iPad as a desktop and attempt to have 20 pages open in Safari at once, and when they reload, come on Mac Rumors and cry like a little school girl ? Only you can decided to wait or not.
