Kasper Jade reporting for AppleInsider:

When Apple finally takes the wraps off its long-anticipated tablet next Wednesday, the device will strike a familiar chord with owners of the original iPhone, with similarities in industrial design trickling all the way down to the handset’s button and connectivity components, AppleInsider has learned.

I think we’ve all assumed that the tablet would look a lot like a bigger iPhone. What’s more interesting is the ports and connectivity that the tablet offers. It’ll obviously have Wi-Fi, Bluetooth, and a headphone jack, but Kasper Jade also says that it will have speakers, a microphone, GPS, 3G, and a 30-pin dock connector.

iLounge corroborates on the design but says that the tablet will have two dock connectors so that it can be docked in either portrait or landscape orientations, also giving added flexibility to accessory makers.
