Pros It connects you to the internet and I played COD4 with no problems.
Cons It did not work at all with Net-flix video. It stated my connection was to slow.
Summary Great for playing games over the internet. No good for streaming live video.
Pros Very fast connection, absolutley no problems streaming hi quality video
Cons To install you have to insert a driver disk, which takes up some storage on your onsole although i think it is minimum.
Summary With the price (when i bought it) being just a touch cheaper than the G version, it is hard to think of a reason why anyone wouldn't buy this. Also with home media streaming getting bigger and bigger it makes sense to at least keep you options open and buy the Wireless N Microsoft adaptor.
Pros Increases the signal reception for my console. I live in an townhouse and my wireless router is posted next to my desktop computer downstairs. Once I replaced my single antenna adapter with the new dual antenna my reception has increased greatly.
Cons The price.
Summary I give this adapter 3 thumbs up for operational performance, lag during game play has decreased and while watching NETFLIX I can maintain high def picture quality. The difference between the 2 adapters is like night and day. The new dual antenna adapter while being the best attachment since sliced bread for the 360 was well overdue on its release and just slightly pricey.
Pros Wireless n standard and improved security over some of the older options.
Cons There are cheaper options and no telling if this is compatible with other devices in the event the xbox is sold.
Summary I read this on this site and didn't realize how many other cheaper options. http://news.cnet.com/8301-13845_3-10408768-58.html?tag=mncol;title
