I have one...I'm fairly new to it, but its very easy to use. I like it a lot.
it take a bit to get used to how to apply effects to tracks and all that, but general navigation is so simple, that learning things like that isnt so bad.
the only CONS i can find...
The screens kind of small
One thing id like to see, is that when you load a song i wish it would remember the volumes that each track was at...i dont think it can do that...if it cant then i havent figure that out yet...
