The only thing I read out of this is that they have no idea for the interface side of things. The dismissal of critique by "we will fix it later, it's easy" never bodes well especially in regards to ui/ux and Linux.
There's problems with the software that need to be solved before we ship, but it's not with the UI side of things. That's not to say that the UI is perfect (it really isn't), but it's functional and more importantly: can be changed at any time, unlike hardware.
