User experience is a no-brainer -- that's something Apple has always done well, and it's arguable that the iPad is its finest hardware from an accessibility standpoint. But price is something else; Apple has made deals and even manufactured its own chip to create the tantalizing mix of performance and cost found in the iPad. Other manufacturers will have trouble doing the same, especially with the lead Apple already has. According to Whitmore, the App Store has also given Apple a head start on applications, deals with media companies have brought big-name content to the platform, and a slew of competition versus Apple's one-device strategy will create problems for anyone attempting to climb the tablet mountain.
That's not to say that there can't be another successful tablet, it's just that if anyone wants to have another iPad, they've got a lot of work ahead of them. That's not surprising -- Apple has already reaped the benefits of its early grab at a tablet-style computer, and there are much more earnings where those came from.
