There are no details on an Apple tablet. Apple have not said they are releasing one. Analysts have been predicting one for years, and have found themselves to be wrong every time.
Microsoft Courier is currently a prototype with a lot of marketing fluff around it. Anything can be made to look good in a 2 minute demo, and Microsoft has a history of taking cool ideas and then dialing the suck up to 11 on them.
So you’re asking us to speculate on whether a gadget that exists only in Microsoft marketing puffery will be cooler than a gadget that does not officially exist. I think you need to close the Engadget window and go outdoors for a bit.
