Not likely at all.I guess it all depends on whether or not you're used to playing a weighted hammer action piano style keyboard or not.
I use my Kurzwel PC3K8 as my master keyboard for recording and use the QX49 in the bedroom for practice and general inspiration when I'm watching TV or listening to music.
You might seriously find yourself in trouble if you ever end up owning a true digital piano man.

Only would consider upgrading to a Korg PA4X and buying another like a Roland Juno 61.
The Midi is only really for my Grandson to use with the Apps on my iPad and Roland Katana mini amp and for me to take this kit to a friends if I cannot be bothered hauling the Korg around.
Remember for me keyboards are just for fun, guitar and bass are my first loves.
