The G1 is an interesting device from smartphone maker HTC. Here are five things about it that are really cool.

1. Capacitive touch screen: The G1 has a capacitive touch screen just as the iPhone does. This means it is very responsive when you touch it. It also has haptic feedback, to let you know you've performed certain actions.

2. Easy-to-Use Interface: The user interface was intuitive at first blush, and didn't leave you wondering, "Why did they do that?" The layout was easy to understand, and simply made sense.

3. Great Google services integration: Seriously, it couldn't be any more tightly knit together. Gmail, Google Map with Street View, Google Search, YouTube, and others are built into the UI and work great.

4. Having a keyboard: I like my iPhone, but typing on it can be a serious pain. The G1 has a real, physical keyboard for typing out e-mails, instant messages, and test messages.

5. Upgradability: The Android UI is open source, and can be upgraded and added to over time. Google, T-Mobile, and HTC pretty much promised as much.

Stay tuned for five things not to like about the G1.
