iPad for Preaching - My Wish List

There has been a lot of interest in the iPad (affiliate link) as a tool for preaching and sermon preparation. The Logos 4 bible software is running on the iPad and doing a fine job of it. There are some controls for Keynote and a version of the Apple presentation software for the iPad, but right now they aren't quite ready for prime time.

According to Engadget, this Christmas will be full of tablet computers, not just the iPad, but Windows 7 tablets, the Samsung Galaxy Tab, maybe even the HP Slate with WebOS which they acquired when the bought Palm.

Here's my wish list for a tablet that would be ideal for preaching (in no particular order):

• Cross platform presentation support. I want to be able to control a Mac or a PC with my tablet.
• Wireless connection to a computer that will run the presentation.
• Slide preview, notes view, and a user-definable section for additional information (twitter feeds for people to respond to the sermon in real time for example).
• Full file import and export control. I want to be able to save, copy, move, and edit files with my tablet.
• Bible software integration. I don't need all of the commentaries from my full version of Logos, but I want the bible available on the tablet.
• Full function sketch pad for drawing out storyboards of slides.
• Docking and file sync that I don't have to think about. 

What would you add to the wish list?
