I'm quite interested behind the logic behind 'Pretend to hold a pen or stylus in your hand and write something' with this multi-touch.
What do they mean? As in, just hold your hand in the shape of a way you'd hold a pen, and the screen will pick it up from your hand/palm shape? That surely is way too imprecise for writing? Anybody whos tried drawing on the iPhone/Touch knows what it feels like.
But what about actually holding a stylus or pen? Anybody who knows anything about multi-touch knows it is a capacitance surface. Which means it detects the electric signals in your fingers to rely on input, which makes it much more smoother than a pressure based system. Nintendo DS and PDAs are all pressure based, which allows them to use styluses, but also means when you use your finger, you have to press just that bit harder, and not this 'glide your fingers' beauty from multi-touch. Could they possibly make a battery operated stylus?
But we all know what Steve Jobs thinks of styluses. 'ew'
If Apple finds a good way around this then bravo, because it is genuinely a concern. Both technologies are great, and multi-touch is simply an amazing technology. But its still in its infancy, and it still has niggling problems. Like this.
Rant over
Otherwise this sounds really cool, albiet what we've heard for months.
