Yes even i had a dilema between 12GB and 500GB. I went ahead with 500 GB as i knew that 12 GB wont suffice.I bought the super-slim a few months ago and have 3 gripes with it mainly:
1. The top-loading disc cover feels pretty darn flimsy and cheap. When you manually close it you'll realize that you will need to do it gently each time due to chances of dislodging it somehow. For a 16k product this just isn't acceptable.
2. The 12GB flash memory just isn't enough! I have been playing quite a few titles on the PS3 lately and almost each time I have to clear space, delete past game files and then load up the next title. The waiting period for deleting each game is also around 10-12 minutes (approx.).
3. The top layer design (the non-glossy part) is also a dust magnet and you will need to keep it covered when not in use or give it a dust every now and then. I tend to keep it covered with a soft piece of cloth.
IMHO, go for the slim version if you can get hold of one or else pick the super-slim version.
