Sony BDP S570 vs. Sony BDP S470

[Thesis]

So, before the holidays, I was looking for a Blu-ray player to replace my PS3. Therefore, I managed to stop by my local best buy store and I picked up the S570, which happened to be on sale. However, after the holidays I bought a 3D-TV and was given the S470 Blu-ray player as a bonus after purchasing my new 3D-TV. I still haven't opened both Blu-ray players, though; I'm not sure which one to go with. Therefore, I was wondering if any of you had any suggestions for me as far as choosing the Blu-ray player that's suitable for me. I know the S570 is wireless ready, whereas the S470 isn't. Besides that difference, which Blu-ray player is better? Or are they the same minus the wireless ready option? I would appreciate your help. Thanks!
