No, just upgrade if you want, or stay on that version.
Alternatively, you could install full CFW on your PS3 (if it's compatible) although HFW is pretty nice and unlocks after one click.
I now have 5 PS3s (1x 60GB, 2x40GB, 2x160GB) and a ton of DS3 controllers, still, I don't own a Top Loader model for a low price (don't feel like spending too much on a budget model). I thought I'd sell 'em then I started installing HEN on them and kept it.
