There is a quite solid rumor about the next new product from Apple dubbed as Touchscreen tablet. the tablet will be launched in the mid 2010 and will cost around $500 to $700.
The touchscreen tablet will be around 7-inch to 10-inch similar to Kindle DX, with an optimized version of Mac OS X for the multitouch interface.
It’s cool looking and should be just like an enlarged iPhone. Well, I’m not sure how this stuff is going to work, but you will get the update again next year if it happen to be released.
