Yall should be thankful that MS bothered to add Wifi, do you guys remember 360 Arcade edition (no wifi, no HDD )
As for Playstation, it always offered cutting edge components.
yes yes, I know, but I hate incorrect/incomplete info like this... so sorry for the following:
I don't know why you single out the Arcade here, makes no sense.
the 360 Arcade was simply 1 of many SKUs of the FAT Xbox 360.
at launch there were the Xbox 360 (often referred to as Xbox 360 Premium) and the Xbox 360 Core. the only difference in specs was the missing 20GB HDD in the Core package.
the Arcade was a way later bundle that came with a Memory Card and a disc with a bunch of XBLA games and demos on it, but again no HDD.
then there was the 360 Elite, which has a 120GB HDD as compared to the Premium's 20GB. (it also was the first version that had HDMI, but other versions soon also got upgraded with it)
why am I listing all of these? because none of them had built-in WiFi, all of them needed the WiFi dongle to work over wifi. Not a single Fat 360 had wifi, that was a new feature in the Slim model
the Elite came with it in some bundles tho.
.........again, sorry but that post bothered me... singling out the Arcade here was just super weird to me, I couldn't resist
