This move makes sense (especially changing the title of their current flagship to the ipad "air") - should be interesting to see the specs and the design. It wasn't super surprising they removed the biometric scanner from their most recent launch, I would be very surprised if they decrease the DPI on the display just to accomodate a larger form factor. They had a rumor awhile back that the group that designed the Mac Air were going to work on an ipad form factor - wondering if would be similar to the Surface Pro: full desktop operating system w/ attachable keyboard. Not sure if there is a market out there for an Apple Tablet running OSX, but it's intriguing. Oh well, this probably isn't on my shopping list for next year regardless of the price point.
My wife has an iPad, which she carries with her when she has an appointment that requires sitting in a waiting room. It's a good size for that use, but it's a little large for carrying. She also uses it on the couch for games and reading news on the internet, although it's too small and she usually ends up using her 15" laptop. A 7 inch mini for carrying, and a 13 to 15 inch iPad for the couch would be perfect.
Also I really look forward to 64-bit ARM laptops and desktops. Linux is still not quite there, but Linux Mint is close. I really want Linus Mint Debian Edition with Cinnamon to get some of the rough edges smoothed off.
My Lenovo T61 laptop has a COA for Windows XP, and I don't want to deal with XP anymore, and I dont't want to buy a Windows 7 license for a computer that which after Windows 7 is installed will be worth less than Windows 7 costs, so I have Linux Mint with Cinamon on that, and it does everything I want to do with my laptop.
IPad Pro...not a bad idea if done well. I'd bet there will be a Smart Cover/Case with a keyboard...at $99 or so. I don't know if I could dump my boat anchor Wintel laptop, but if the rumored beast does appear, I'll check it out.
