I've heard a bit of negative comment about the 89 's screen being small or difficult to read/see. Any feedback? Thanks

There's no problem seeing the screen. There's a different setup for the screen on the 89 versus am 83/84 but it's definitely easy to see what you're typing and the answer. I guess the only thing might be that there's only one line when you are typing but I can't quite remember if that's hoe the 83/84 is.
