This is what I'm hoping for. At least from the standpoint of external design. Internally I don't expect it to be even close to similar.
iTablet with Intel Atom inside. Mac OS X 10.6 (touch) inside. The Mac in your pocket.
I don't see this happening at all. Mainly because of Apples purchase of PA Semi. Even if the device had an ATOM inside it would still run a variant of iPhone OS. That to simply keep the confusion level down and to make leveraging App store easy.
The thing with ATOM is that it provides a path to the 64 bit world. Right now ARM is 32 bit only. People laugh when I bring this up but the reality is the 32 bit world is slowly drift away. The problem is ATOM won't happen for two reason. One it is way to power hungrey and doesn't deliver much performance for that power. The other is marketing, Apple won't want confusion on the part of the consummers, ARM and App Store make it clear this is not a platform for Mac programs.
Looking forward to the second if it has video-out and USB 2 ports for Keynote and PowerPoint presentations.
That could happen with the ARM based unit also. To be kind of honest though I don't see video out as being a big draw.
As to the two OS's discussed here there isn't a huge difference in capability! Especially when it comes to potential apps delivered. Apps are more about hardware capability than anything and frankly this is where I hope Apple doesn't skimp or at the very least gives us a choice. To deliver the types of apps we all want to see on this device they need to deliver a tablet with a lot of on board RAM, at least two cores and at least 128GB of SSD. This is enough to support just about any presentation. As to that RAM I'm hoping for 1GB but we might have to get by with less. Finally the GPU needs to support the display well and handle 720 & 1080 P video.
Apple has a huge balancing act on their hands here as the device needs to be thin but have a long battery life. Frankly battery life is huge as the device needs to remain connected for long periods of time for web browsing, software updates and file transfers/streaming.
As to you presentations get a laptop. A tablet simply won't cut it for this application. If for nothing else it is difficult to reference the computers screen if it is flat on it's back.
