iPads everywhere

Don’t look now, but the iPads are multiplying like Irish Catholics. Apple’s famously simple hardware product line has gotten crowded as Verizon and the white iPad 2 join the line up. Last week, there were six iPad models to choose from:

Three Wi-Fi models (16 GB, 32 GB and 64 GB) and three 3G models (16 GB, 32 GB and 64 GB). As of March 12, a dozen additional iPad models will be available, bringing the full lineup to 18 models of iPads:

Six Wi-Fi models, six Wi-Fi plus AT&T models and six Wi-Fi plus Verizon models. Not confusing for nerds like you and me, but I can tell you this pile will give shoppers like my mom pause. I also wonder about Apple’s ability to maintain stock across all 18 models.
