Collab is awesome. It's not really for any serious training, it's for evaluating and sharing ML models that (may) need a GPU, and learning. But for many situations, it replaces the need to have a laptop with a GPU - it's good enough for getting set up before you engage the real compute to do serious training. If collab was not free, I would consider paying a subscription for it, which is maybe the end game. They have a paid version now that is supposed to be faster and more lenient about disconnecting you, but I recently read a comparison that said it wasnt worth it.
