I got the Eris and my wife the Moto and it did not take very long to see I liked the Moto better. I returned the Eris and walked out with a Moto for myself. The screen is larger and crisper display. The fact at the time (and still may be the case) it did not support turn by turn navigation was a big turnoff for the Eris. Battery life was awefull tho the droid was not much better until it had a few charge cycles on it. The moto was the one that supported Android 2.01 the physical keyboard is an added bonus (for me). The Moto is definatley larger and bulkier in the pocket.
But I really liked your last line about standards for selecting hubbies.
