Nice, and the price is okay, but the keyboard is not suitable for longer writing sessions.

Even its very own demo video shows a lady on a software with the device AND her laptop (how ironic)!

If anyone has it, how long does the battery last?

I don't have that one, but I have one of the A4 sized onyx tablets. I use it for sheet music, turning pages with an air turn pedal

I get about 3-4 weeks on a charge, albeit with somewhat light use
