Digital Notepad

[WiredUnique]

I'm curious if anyone has or has heard of an electronic notepad. I know they have things like the iPad and other things that are similar but I'm looking for something smaller and much cheaper. I'm thinking something maybe under $30. It doesn't need to do much at all; just have the ability to write notes with it. Basically, I don't feel handing my cell phone back and forth while writing notes because of the area I live in so I thought it would be nice to have something strictly for notes. I can just as easily carry a notepad and pen but my eyes aren't so good so I have a real hard time trying to read everyone's handwriting and all that.

So basically, does anyone know of a small digital writer/notebook/notepad thingy that's fairly cheap?
