<i>Maybe Apple got more closed with the release of the iPhone, but the iPad is more of the same.</i><p>The iPad is an attempt to replace the existing open environment of laptops and desktops. (Yes, Steve does want iPads and their successors to replace general purpose computers. It wouldn't be "the most important thing he's ever done" if it was just intended to be a super iPod touch).<p><i>Oh wait, Macs were locked down too until Apple switched to Intel processors</i><p>That isn't true for any reasonable definition of "locked down". Heck, there were more CPU upgrades available for PowerPC Macs than for Intel.
