Tony, I didn't have PA2x, but the screen on PA3 is plenty large enough for me. I have all the lyrics saved to the internal drive and many are linked to Songbook entries. I seldom actually use them, but they are there for requests and songs I don't do often.
Sure, bigger would be better, but I much prefer the PA3X touch screen to the large Tyros screen that doesn't have touch.
Neither is a deal breaker, but the total package is still leaving me happy until something better comes along.
I'm actually thinking Korg is due for a new TOTL before too long. Hope I'm still around to check it out!
