In a perfect world yes, but not everyone has the skills, time or desire to deal with it. Me on the other hand, if its not wired in my house, it don't work. Wireless is fine for the farking Starbucks book writers and grandmas laptop, but wired is still the best for network throughput and low latency.

Everything in my apartment is gigabit wired and what the landlord doesn't know, won't hurt her.
