Wacom's Bamboo Tip is a fine-tip capacitive stylus for Android devices
You can get a cheap capacitive stylus that works with your phone, but they're not much more precise than your finger. Wacom says the new Bamboo Tip is in a completely different league. This stylus has a small tip more like what you'd see on an inductive stylus like the S Pen. However, it works with any phone or tablet. It's a bit spendy ($50) for a stylus, but it's available now.
The Bamboo Tip has an aluminium body with a slim replaceable capacitive tip. There's a rechargeable battery inside (microUSB hidden on the end) that lasts for 20 hours. However, this is not a Bluetooth stylus. There's no pairing to worry about, so we're theorizing the battery is necessary to generate the capacitive effect on the tip's small surface area (known as an active capacitive pen). Most capacitive styluses are much larger and don't need batteries.
