I think the Advantage2 is still more ergonomic for most users since the keys are shaped in two curved wells which help keep all rows comfortably in reach without forearm or wrist movement. I have long fingers but someone with shorter fingers should still benefit in relative terms. My understanding is that the two curved circuit boards are expensive to produce, which may justify some of the $370 (wtf) cost. I bought mine used from Amazon Warehouse (used, good return policy) for $220 when I started experiencing RSI and have never looked back.
