That's the key, here. All these guys got to show off first, but only because iSlate rumors have been floating around long enough for everybody to whip up something as a preemptive "in" on Apple's potential market. They've probably been at this for the past 6-8 months at best, while Apple's been developing this thing for well more than a year. There's a reason they didn't buy into the netbook craze, and it's because they saw a much more lucrative market opportunity that others are just now beginning to see. I still have no idea what it would be best suited for, and by the looks of it neither do any of Apple's competitors, except perhaps Lenovo, which is clearly going in its own well-defined direction.
Apple has two things going with this:
1. They know touchscreen interfaces better than just about anyone else (not just the hardware side, but the software to make it feel natural to use)
2. They've had a several-month head start on the rest of the industry.
Apple is playing its cards close to its chest, and everyone else might have shown their hands a bit too soon.
This game doesn't really begin until Apple says it does, and everyone seems to know this, even if they won't admit it. Perhaps Apple really does have an Ace up its sleeve this time.
