I am betting on a lot of updates coming in the next 6 months. From the MBP and MB to the current iPod Nanos and possibly the Touch.
Some of the upgrades I am expecting are new some kind of new user interface, something like optimus keybaord possibly on the MBP and MB line. I can also see an improvement on Nano and Touch capacities.
As for the tablet, I am doubtful of a full fledged tablet and read a great article about it today, they just aren't conducive to actually doing anything for prolonged periods of time. And, While I am sure they are great for graphic design and such, would it be difficult to work when your interface is having your hand in front of the screen?
All that being said, does anyone think they will break into the e-reader market and compete with Amazon and Sony using the ITS for distribution? If they did, I could see this as a tablet like device that would work for web browsing and email, but wouldn't be a full fledged computer.
I hope those opinions don't ruffle any feathers.
