Some oddities in the chart -
"Zoom H2 - simultaneous record tracks = 2". Well, that's 2 stereo tracks, so the figure for the rest of the recorders should, on that basis, be 1 (I'm not sure about the H4). The fact that it has a 4 channel mode is noted at the bottom of the chart.
"Zoom H2 - Analog outputs = 1/8" line, 1/8" phones" - should be "1/8" phones/line"
The "Computer Connection" row could more usefully be labelled "USB2.0 speed" and distinguish those which are "high speed" (fast) and those that are "full speed" (slow, like the H2).
