The Boogie Board (about $40 on Amazon) is basically a small chalk board without the chalk. It's a black slate that you write on with any pointy object, like your finger, a capped pen or the included stylus.
It's like an Etch-E-Sketch in reverse that you draw on with a stylus. Instead of shaking it to blank it out, you press the little button.
Who's it good for:
What's good about it:
It's light, it's portable. It turns heads--literally everyone who has seen mine asks me about it. It's great for practicing my handwriting.
What's bad about it:
Anything hard that touches it (not just the stylus) will leave a mark, so it's not that great for writing notes. The contrast is not all that great--it's readable, but not as easily as real paper. Maybe you could leave it by the table for phone messages (does anyone do that anymore?) Or stick it to the fridge so family members can leave messages to each other. You can write a grocery list on it, but if you're not careful you'll pick up enough random marks to make it difficult to read by the time you get to the store.
One big drawback: You can't erase just a part of it--when you press the button it erases everything. It's all or nothing.
Helpful hints: There's a little slide switch on the right side that disables the erase button.
