Hipster PDA

It's been about a month since I switched to the Hipster PDA. It's working great so far.
- They don't need batteries
- They don't need maintenance
- You don't need good light to read it
- You can have as many as you want, they are so cheap
- You can customize them any way you like
- You can write on it. None of this Graffiti rubbish, just your normal handwriting
- They don't break
- You can make your own interfaces and applications
Pair the Hipster PDA with the D*I*Y Planner cards and you're golden.
