Clearly produced in flash with what looks nearly like a cardboard cutout of a hand, this mockup of a tablet and interaction version of of Sports Illustrated is "Coming in 2010".
My normal distrust of "design prototypes" is tempered by the many rumors of Apple's tablet, it's release next year, and the fact that nothing you see in this mockup is beyond the technical capability of an iPod Touch with a 10" screen. Add to that that Time Inc. boldly claims it is coming next year.
I'm particularly interested in the form factor. I read a surprising amount of junk on my iPhone and it does that quite well, but a full color reader at this size would satisfy all but one of 'e-reading' needs (tech books, full color, etc). That last thing is to let me keep my reader powered ON during takeoff and landing.
