Anyone who has one of the now inexpensive NAS cases or a home file server will benefit from inexpensive 802.11n. Doing file transfers over vanilla or even MIMO 802.11g isn't exactly the quickest or most fun way to do this.

The same people (techies) who would install DD-WRT are the same people who would have a home file server of some kind, probably with music and movies on it. 

I'd have to say that if you have anything less than a Mac and an Apple TV, don't bother buying it since a cheap Linksys router would work just fine ;).

Core2Dud* G is very slow for home usage.
For example after switching to N i can stream HD movies from my PC to my MBP, when i lay in my bed 10 feet away.
Also i can use my 30mbit internet tirelessly. G gave me only like 2.2mb/s, now i get 18mb/s its around 144mbit :)

Didn't think so! If you have anything more than a mac and apple tv at your home, don't buy it!!!

Go for Linksys WRT54GL--best bang for the buck. Who needs 11n at home anyways?
