We introduced a similar iPad stand with the following, but apparently if you want more functions, the following Dock Minimal tablet stand will be more suitable for you.
Dock Minimal is multi functional tablet stand that fits for various tablets including all models of iPad, iPad mini, Kindle, Samsung and Nexus tablets and more. As we can see from the images, the tablet stand consists of two main parts including a hourglass-like base made with ABS plastic with a light rubber coating and an aluminum kickstand. Using the kickstand and custom holes on the base, the tablet stand is able to hold your tablet in portrait or landscape viewing mode along with over 20 different working/ viewing angles, while its 4 connector fittings make the tablet stand double as a practical. Apart from that, the kickstand also features a hidden in order that you can conveniently doodle on the touchscreen.
At present, the designer of Dock Minimal is raising fund at Indiegogo. Pledging $$25 will let you own the tablet stand. If you’re interested, jump to Indiegogo official site for more details or check out the following demo video first.
