A GUI is of critical importance for the next level of adoption.
How many Bitcoin users do you think still use QT?
I run QT still

is that bad?
Me too! Id does what it is supposed to do. For Monero, I also have the CLI wallet installed, but I would never get my wife to use it. But she can handle Bitcoin-QT without problems -> GUI wallet is a big deal IMHO.
BTW: there may be a small, shy triangle breakout. Let's see how it develops.
