I don't know about the rest of you, but I can't see myself getting the slim PS3. I like the Digital Media center on my 80GB Motorstorm PS3 too much. It makes it so much easier to transfer photos, videos, music, and updates to the PS3.
The faster loading times are very nice, but I agree with broy4686 faster install times would be an even bigger plus rather than loading time. Even still, the Slim PS3 not having the Digital Media Center (although there are fat PS3s without the DMC) is a big turn off for me. My grandma's PS3 (my grandma is hardcore like that) doesn't have the DMC that my PS3 has and it's a pain in the ass using the USBs to transfer stuff to from say a Digital camera or micro sd card.
Also I noticed that the Slim PS3 has two fewer usb ports than mine has. My PS3 has 4 usb ports! Making it much easier to charge four controllers than say a ps3 with only 2 usbs.
Although... the slimline is supposed to weigh a LOT less than the original, and that might change my mind, but still fewer usbs, no DMC, and the hard drive being in front kinda still bug me. As for the textured non fingerprint showing surface, I can just buy a PS3 skin and not have to deal with that (most skins only being around $14.99 very cheap).
