WiFi isn't just for Internet, you know. I have multiple computers in different rooms at my house. My options were to drill holes, run, cut & crimp Cat6, buy some Gigabit switches, etc - or use WiFi. I went with WiFi at first. 54 Mbps IS plenty for Internet. But then I started copying games, ISOs/software, and multi-gig movies from one system to another. I started copying my movie library from my main system to a system by my TV. Suddenly, it became PAINFULLY obvious that WiFi would NOT cut it. Even when I tried to stream HD content from one system to another, it started to get choppy. I ended up drilling holes, running cable, etc. 1,000 Mbps is a lot better. That is still the weakest link between the systems. I get 30-60 MB/s that way, when I know I could be transferring 70-110 MB/s with my hard drives. If it was WiFi, a 2+ Gbps connection would be ideal. If it was stable, and it reached all rooms at my house (some are 2-3 rooms away from my current AP). Until I can get that, wired Gigabit is the way to go.
