Most analysts seem to agree that the iPad will maintain its lead in the tablet market.
There's pent-up demand because a new device was widely anticipated. They've made enough incremental improvements to do well. If you look at people who've opened their mind to tablet ownership in the last three to six months, they were probably hesitant to buy one knowing this was around the corner.
The resolution of the camera is quite important because this will allow for streaming and video at higher quality. The processor is so much speedier. That's going to allow game makers to develop a much richer experience. That's a negative for game console makers, like Nintendo.
The iPad 3 is definitely the strong tablet offering in the market. I would expect strong growth of iPad sales to continue. Now that Apple has adapted 4G on its iPad I think a 4G iPhone is next.
