PDAs.<p>- ASUS MyPal (which I have and it <i>still works</i>) had much better battery life than any of the smartphones I ever owned.<p>- It had a consistent interface that wasn&#x27;t a confusing clusterfuck of random shapes and expectations.<p>- The hardware was durable and extensible through compact flash slot.<p>- I could install software on it without going to a centralize store or going through some elaborate jailbreak. And while there wasn&#x27;t a million free apps for it, there were good free apps, and finding them was actually easier than finding something on Google Play.
