Microsoft Xbox 360 S (250GB)

Pros: Smaller footprint

Cons: Still requires proprietary video cable
Just as warm and noisy as my old one times two.
Extremely poor......read useless........wireless performance
Tech support aware of wireless issue and cannot fix it
Can't use old Xbox proprietary memory cards

Summary: I've owned an old an Xbox 360 for a long time. It was a great console and I was planning on just upgrading the hard drive to a 250 GB one which are available for the old models. However, mine got the red rings of death and it was almost dollar neutral to "upgrade" versus getting a repair.
Now please bear in mind before I continue that my old Xbox 360 sat in the same place as the new one, is in proximity to the same devices as the new one, powers from the same outlet, and downloaded via wireless just fine. Laptops in the vicinity of this new Xbox d/l just fine via wireless.
This new unit can't download a thing via wireless. I have attempted to download games from XBox live multiple times and the downloads are so slow it would literally take a whole day just to download a 5 GB file.
I called tech support and the first person told me to get an Xbox wireless N adapter. That didn't work. I was then put in touch with am Xbox network support specialist....in fact I've spent at least an hour on the phone with two network support specialists on two separate occasions. They both independently determined that there was nothing wrong with my wireless network and that the purchase of the adapter was not necessary. So they told me to replace the unit which I did. I brought the new one home, set it up and had the same issue even worse. Fortunately, my home was wired for an Ethernet when it was built so I was able to tap into one of our Ethernet cables in the wall behind the console, terminate the cable and connect wired. The d/l speed isn't great and I really didn't want to drill a hole in my wall to fix this, but it's acceptable. All the tech support people I spoke to at Microsoft independently acknowledged that the poor built-in wireless IS a known issue. So if the console is known to be defective why not recall it or replace the defective ones?
So if you're considering "upgrading" your old Xbox 360 console, save your money and just buy a 250 GB hard drive for your old one like I just did for my other console. The 360s is a truly a downgrade.
