What does battery life have to do with tablet inputs? Tablets (at least, the typical kind and not the kind with built-in screens like the Wacom Cintiq) use relatively little power (much less than, say, charging your phone via USB).
Different tablets use different technology. The Wacom tablets use an inductive charge (from the tablet itself) to charge a capacitor on the pen. This means that yes, you need a special stylus. However, because of it, you can get much more precise location and pressure readings. You also don't need to change any batteries in the stylus, as it's powered "over the air."

- ben_straub 17y agoSomething like 95% of TabletPC's use a Wacom panel for the pen input, and those panels have similar characteristics to the Wacom consumer tablets and Cintiqs.
- ben_straub 17y agoWell said; I work at Wacom, and I don't think I could have explained it better. :) Powering the pen does consume some energy, but I believe the panels used for TabletPCs can actually be classified as "Low-Power" USB devices, so the drain isn't nearly as much as, say, the hard drive. I'm not sure how efficient the Windows Ink code is, but our driver, which hasn't taken extreme pains to be performant, peaks at about 3% of a 1GHz CPU when the pen is in range.
- listic 17y agoWhat does battery life have to do with tablet inputs? Oh, nothing. There are two distinct questions of usability that I'm interested in. Except, that X60t tablet is different model form X60 laptop and may use different CPU and battery model, which of course impacts battery life.
