Disadvantage: Because the keyboard is still optimized for WebOS missing some important buttons. I'm missing the screen up / down button. In addition, there is no F-keys. Some WebOS special keys (eg image brighter / darker) I could not prove anything with Sinvollem. On the System button (?) I put old. Typical WinTasten there is no course.
Conclusion: As I was looking for the only Bluetooth keyboard flat which a full size, keypad includes, but other remote (space intensive) keyboard parts saves (so small dimensions achieved), while also being more cost-effective. Had the keyboard now NEN half a year in harsh, mobile applications, and it worked always impeccable. Who has not used for a WebOS product but should remapped keys in his system as he know.
