Which is of course why the iPhone was so brilliant. Current stylus technology still can't create a paper-like, pleasant writing experience, while capacitive touchscreen technology can create a pretty good direct manipulation experience. People aren't going to commit to getting over the learning curve after the unpleasant in store experience just because of the theoretical advantages of the stylus.
I'm used to the textured feel of paper and the pleasant friction b/w the pen and paper when writing on it. On glass, it just slips... However, I guess that's just something of a habit. Maybe for future generations, brought up with touchscreen enabled laptops, it will feel more natural.
I thought power steering was still hydraulic. Are you saying we have "fly by wire" cars?
The stylus does have some lag to it and you have to get used to not seeing your writing show up immediately. When you see your writing hasn't showed up yet you tend to stop or slow down which isn't necessary, just keep writing and trust it will show up. I know that sounds terrible but it's really not.
