Apple invited the media to a preview event of the iPhone 3.0 OS taking place tomorrow. ComputerWorld's Seth Weintraub writes that Apple might have a surprise up its sleeve and unveil the very long rumored Apple tablet.

Apple might unveil a 10 inch device that basically resembles an iPod touch. The 10 inch device would not be a full netbook, but would be a very nice media and online device.
Apple is also rumored to open a premium App store selling apps for around $20. Possibly Apple is going to expand the App store concept also to all Apple computers. Why just have an easy way to buy Apps for the iPhone and iPod, if you can also offer all the OS X apps in one single place via the iTunes infrastructure.
