It won't be long, the iPad and iPhone is mostly built from standard components, ARM chips, the Samsung Hummingbird SoC (or a very close relative) etc.
If you've been looking for an ARM "smartbook" you'll have noticed that they are frighteningly thin and have amazing battery life. Unfortunately the inability to run Windows meant no-one was prepared to sell them. This year all those exact same smartbook systems are back, this time minus the keyboard and running Android.
edit: just to be clear, that last line isn't metaphorical, the product demonstrators at thing like Computex are saying this is the exact same hardware as our smartbooks we've been previewing but in a tablet form factor.
