Agreed. That was the point made by Matt and Scott in the videos. LR is made specifically for photographers. Photoshop and its companions Bridge and ACR can be used for photographers but they are for general purpose graphics works. The same goes for Pixelmator.
So if Adobe has spent time and money to purpose build a photography DAM with non destructive editing, that does round trips to plugins, it should be a strong candidate for any photographer. Granted, one size does not fit all.
