You know what the iPad really needs? Storage.
I don't mean more memory, though obviously there's never enough of that. No, the iPad needs a place to store your keys, stylus, sync cable, earbuds, and all the other detritus that typically clutters up your pocket, purse, or carry-on.
While we're waiting for Apple to invent the iDrawer, check out Kickstarter project Smart Cargo for iPad. This clever storage bin integrates with a Smart Cover or Smart Case to keep all your important stuff close at hand.
