HP Palm TouchPad and BlackBerry PlayBook share similar user interface
HP Palm TouchPad was announced at the recent "A New HP World" event in Shanghai, and with Research in Motion's BlackBerry PlayBook launching next month, it seems that both tablet devices have some things in common.
It is sometimes inevitable that similarities do exist between products, and for consumers, it doesn't really matter to them who is copying who. End of the day, whether the product will sell depends on its usability, features, performance and price tag. According to HP and RIM, both companies have said they will continue to optimize their products to bring the best experience to users.
