I've been hearing a lot of good things about the new Wireless Draft N routers. I plan to replace my Linksys WRT54GS router and when I do that I plan to get either a Linksys WRT150 or WRT300N. To those who've used either, what can you say about the performance? Do the new N routers work well with other G devices? What advantages will I get if I'm using a G device and an N router?
