Beakybird, your summary of the differences above seems to be right on. I agree with all of your observations. I really am looking forward to Wednesday, when my 2100 is due in. I will have both machines, at least for awhile, and will be able to make some comparisons. But, with all of your performing experience on the 2000, I expect you will be able to supply some terrific insights into the new keyboard when yours arrives, so don't hesitate a second to give us all your evaluation. I will surely steal it and put it up on the psrtutorial site along with George's first comments. I hope that, between the two of us, we may be able to lift some of the clouds of uncertainty about the new 2100.
