I agree, up until my first-gen PS3 failed in January this year I used it for everything gaming and media related, especially streaming local content from my media server. What sold me lock and stock at the time was the built-in blu-ray player, the whole package was a fantastic all-in-one bargain when I built my first 5.1 surround system with 40" 1080p LCD telly back in 2007.

Maybe some of the loss of functionality in the PS4 could be re-enabled with future firmware updates if there's enough demand/complaining.

Personally I'm more likely to get a replacement used PS3 once the prices dip a bit more.

They are.
