Wow, some major speculations on that 7 things article. I won't even mention the horrible grammer in the article. But come on....standard USB port would mean the ability to install drivers, either by the user or by apple...they are not interested in either. Camera...maybe...but the iPod Touch took 4 gens to finally get one! Carrier choice...well if that happens your choice will be ATT or Verizon. The screen on the iPad is the same screen as is on HP's $2500 Dream Color display....good luck making it better quality. They may slightly alter the body...but I think it feels great...so I don't thing its needed...again, total speculation. Someone needs to visit the App store more...there is already photo and video editing software avialable for the iPad.
Dual Core proc??? Not a chance! One of the key features of the iPad is battery life....add a second proc and that goes down the drain. Also there is NO way that a product that is still in its infancy and is gradually gaining a HEAVY iPad 1G user base would alienate everyone in a single generation! Apple's MO is second gen products add more memory and nothing more....3rd gen will get a beefier proc and maybe more memory and 4th gen is a redux while phasing out first gen.
My speculation tho is that 2g will have more storage space and maybe cameras (not holding breath). After that the MacPad will be released as a Dual Core 8 Hour battery with Mac OSX Lion (basically a MBA without a keyboard)...at that point I don't really care where the iPad goes since I won't be using one anymore.
