Switching seats

If you switched from an infant (bucket style) carseat to a convertible before your baby outgrew the infant one, why did you decided to?

I have a little guy who is 8.5 months, so I will probably be able to use the infant seat for a while, but I am thinking of switching to a convertible now. He is nowhere near too big for it yet, but I think he may be more comfortable and like it better. The only thing holding me back is that I spent the money and could get more use out of it.

What did you do? Thanks.
