I had been using QUBE's on a Lenovo X230, which in my opinion has a TouchPad that is difficult, and a keyboard that is not very pleasant. That one does not like an external wired mouse. Keeps disconnecting mouse.
I just put QUBE's on a 2016 Alienware 15 R2, which has a Core I7 Skylake Processor and 16 GB RAM with an M2 SSD.
So much nicer with a more easy to use TouchPad and Keyboard. Not to mention faster.
Problem is of course, this is only 70 percent of secure. I do not have hardware with free drivers, and some other things like that. But it is smooth.
I wanted to say to those who are trying out QUBE's, the hardware one uses really changes the experience. So don't give up. I also hope that soon we will have tenth generation processors with hardware that has free drivers.
