Windows / Android dual boot tablets

Has anyone tried any one of these tablets? There are several models that have both operating systems so you can choose which one to run and be able to use any apps just like on a regular desktop or laptop in the case of Windows. I'm thinking on maybe buying one of these but I have no idea if they are reliable or not, as from what I have found none of the big brands like Samsung have devices like this.

I have one and its pretty cool

Even I have noticed that none of big brands is having such device with two operating system. one of my cousin purchased such device, and for him it is working good so far. I don't remember the company though.

I haven't tried doing a Windows and Android dual boot on my tablet but from what I have seen on YouTube, it's not really a good idea due to huge incompatibility issues as well as performance issues.
