I want to develop a small device. That I can write on with a stylus, and save what I wrote either to a flash, sd or on board memory; and load it up later. Is it possible to just have a writing pad, and be able to save and load? If you need more information I wrote a whole manual on what my idea is. I just do not want to post it all, and make everyone overwhelmed.
Didn't Nokia already do this with smart paper?
Even if they did, I do not want to purchase their product. I want to design my own, so that I may learn. This is for learning, not for making money (at least for me). I want to do this in order to learn how to work with the Arduino better. How do you suppose I go about doing this?

OK, go ahead, I was just trying to advise you that there is prior art.
I was also just wondering what the point of your post was.
What I see is spam. This section is for people looking for advice on how to begin a project, and or the feasibility of their project. You have helped me with neither. I just see a person who is attempting to raise their post count. As well as pick on a new person, that does not know everything about what they are doing. What you are doing is mean.
You're absolutely right.
I've got over two and a half thousand posts and I JUST WANT MORE, so I pointed out what you want to do has already been promulgated, patented, marketed and sold.
Meanwhile, you posted a vague WIBNI with no detail whatsoever, and now you've increased your post count 300%.
Trust me, I've seen bigger ideas than this, and not been overwhelmed.

As has been pointed out, yes, this is possible. Whether YOU can do it, or not, only you can decide.
Your attitude so far, though, would have me believe that the answer is no.
You would need a touchscreen, and some processing capability, and power, and storage. Perhaps there are implied requirements to be able to upload the 'writing pad' notes to a PC. To me a smartphone would be the natural platform for this.
On a hunch I asked Google whether anyone else had thought of this and it won't come as any surprise to learn that they have. There's nothing preventing you from writing your own smartphone app if you want, or even creating your own platform based around an Arduino and implementing it on that - although it seems to me that you would end up having to reinvent quite a lot of stuff to get something working, and a heck of a lot of work to get that up to the standard of the existing cheap/free smartphone apps. But if that sounds like a fun thing to do, then go for it. You'd certainly learn a lot along the way.
Pointing you at something that already does it should give you a list of the kind of parts you need!. After that its just a simple ( 
case of top down design.

lasr week i saw simple ic and you did not even have to touch the sceen just hover above. a display is needed, yes possible with arduino
I'd look at the LCD manufacturers (I prefer New Haven personally) to find a suitable touchscreen and work from there. Though I would hold in the attitude. Unsure on if the Arduino can handle this, but if all it was doing was reading and displaying, assuming it can do the read, it can probably handle it.

I'd look at touch screen device manufacturers, like Atmel or Synaptics.

Thank you everyone else who has been helpful. I do not like it when people beat around the bush. My question was: "Is it possible?" And is has now been answered! Thank you! Telling me something has already been developed does not mean I cannot do it myself. That is like saying, because Ford created cars first, no one else should do the same. Or better yet, because light bulbs exist, we shouldn't attempt to make new light bulbs (LEDs anyone?) That is what pissed me off about that first guy. Thanks to everyone else for the information!

You're asking for advice on project feasibility. Don't be surprised if people question whether your project is necessary, since you've given us no clue that you're aware of the alternative existing solutions or that you're doing it for fun. You have no idea how many people come here and propose using the Arduino for things that it is completely unsuitable for, or to solve problems that can be solved far better by other means. Just because you're thinking of using an Arduino does not mean you need to be hostile to suggestions to consider other options.
