I am about to call best buy to replace my MGS4 80gb PS3 for a slim. With the replacement i will also be getting $200. Now i am a little upset because i am loosing backwards compatibitlity, 2 usb ports, memory card reader that i actually use, and a nice sleek design. Can someone actually tell me some benefits of owning a slim? Does it have better audio, ports, anything at all? Is it only a downgrade?

Well there is less power consumption and a bigger hard drive (120 GB vs 80 GB plus it's more reliable. It's also smaller.  

Wouldn't this be a question you ask before you decide to replace your old PS3?

-edit-

To answer the question, nothing other than it's smaller, quieter (major one for me, my old PS3 was a jet engine), and uses less power. 

Oh, actually, there is another thing-- they did the incredibly wise thing of getting rid of touch senstive buttons!  Yay!  I hate those things.

Well I have a slim and the only thing thats better then my old 80GB PS3 is the Bravia Sync that works with my TV. Besides that nothing really. More efficient CELL...I don't know, I'm just trying to make it seem less bad for you.

I really dont want to. But my ps3 fan kicks into high gear after 5 minutes so im guessing it will get ylod soon or something

That's about the same state my 80gig BC PS3 was in when I decided it was time to get a Slim. :-p

I don't really care about losing the USB ports and I *hated* losing backwards compatibility, but I also hate touch sensitive buttons and my console being louder than my TV.

really? I actually like the touch sensitive buttons. It makes it feel more next gen and a future proof machine.

Oh yeah, I don't think I've ever had a device where I like the touch sensitive buttons, they're actually the biggest reason I don't want a new 360.

My TV has a touch sensitive button and it's hidden so well I still don't know exactly where it is (I find it every now and then when I'm dusting), my monitor has one and it just plain doesn't fucking work half the time, they're a pain in the ass on my old PS3 when trying to turn it off, and I just plain don't like them.

They're cool in theory but they're either too well hidden, turn on at the worst tirmes, or a pain to use.  I was overjoyed that the PS3 Slim didn't have them.

Also, I forgot to ask-- what do you mean by getting $200 back?

I haven't actually sold my old PS3 because it's technically still working and I plan to sell it around Christmas for at least $300.

well i bought it for $500 and when i called best buy they said they will send me a best buy card containing $540. And the new ps3 slim is only $300!!!
