I think Apple can do it.
Here's why:
1) when the amazing Apple IIe was considered the computer that gave Apple a fortune and could not be surpassed, then came the Macintosh
2) when Macintosh seems to be the all time ultimate all in one, then the Blueberry iMac comes out reinvents what an all in one computer is
3) just when you think Apple has done well with computers, they raise the bar higher and finally become a market leader with the the iPod/iTunes/iPhone
There are other reasons why Apple rarely fails to amaze, and by now most should realize they are not just a computer desktop and laptop company. I have a feeling this tablet will be more of a personal object with amazing abilities which will be more part of a person vs. being a computer. Apple's reputation as just only a computer company is over. Apple is one of the top technology companies, if not the top technology company along with Sony. While Apple is not as big as Sony, I wouldn't doubt that if one day Apple could also make great car CD/MP3 players that are standard at car radio joints, have a record company that signs big artists like Sony, or even every form of consumer electronics out there (Camera, flash cards, digital media storage, etc).
