I have a slim and a phat 60 gb both get the same very slow wireless speeds but normal wired. GTA took close to a hour to download wired on my phat but 8 hours wireless on my slim.
Interestingly enough I have never compared my PS3 Slim's wireless vs wired. (I have compared my Xbox 360's because the original models didn't have the wireless built in and made you buy a $100 doohicky.) Streaming media, DLC and movies download on the PS3 comparatively to my wired Xbox 360. Full game downloads are another matter. I guess next time I buy a digital PS3 game I'll have to hook the console up to the wired network and see if that makes a difference.
If you're omnipotent and all-powerful...why would you need to REST? On the 7th or ANY day?
