Hi Brian:

Some good articles-

CNET- somewhat dated, but good (c2005)
http://reviews.cnet.com/4520-3243_7-5124418-1.html?tag=nl.e501

Excellent article from Laptop Magazine (c2007)
http://archive.laptopmag.com/Features/Common-802-11n-Myths-Debunked.htm

Wikipedia article- very thorough and up-to-date (c2008)
http://en.wikipedia.org/wiki/IEEE_802.11

The bottom line- the 802.11n will be the way to go when the TGn workgroup finalizes the standardization process in or after November 2008. The 802.11n is 4.5 times faster than the current sweet spot, the 802.11g. If you get something NOW, go to the 802.11g, but for 2009 probably go for the 802.11n.

Cheers,
Al
