A:Answer It takes a USB connection.
My daughter uses this with her art, and she's pretty happy with it, the cable length is kind of short in my opinion, but easily remedied with a wireless USB connector (I think this version can be upgraded? but I'm not 100% on that). If you plan on using this with a laptop, so long as the pad is placed within a foot of the laptop, it should be fine.
If your laptop has a bluetooth connector and a touch screen display, I recommend the Bamboo Ink Smart Stylus (draws directly on the screen, no side pad! I love it!) linked below.
