It's not just oversized carry-ons. There isn't space for every single passenger to bring a full-size (but within stated limits) carry-on plus personal item. And with carriers charging for checked bags, it's worse than it would be otherwise.

That said, as an infrequent flyer, I do like you and just wait in the terminal until the end of boarding. No point waiting in the middle of the line - that's the worst of all options. I also make sure my personal carry-on (usually a large laptop bag) has my toothbrush and clean socks, just in case I get stuck checking a bag at the gate.

But, given the option to board early without charge, I'd take it.
