It's not the size that matters, it's the layout and flow. Although, I admit, there isn't a single person I know in my area playing a Wersi, so I can't comment on that one. But I've played everything with a touch screen that is widely available. G70 is better by far.

And, arranger manufacturers have ALWAYS made arrangers with features less than 1% of the users ever use. I see no change in that at all. In fact Roland just added in to the BK-9 OS a bunch of stuff I'm pretty sure hardly anyone will ever use... but I will!
