The same thing is pretty much true for graphics as of about 10 years ago. Most consumers who don't play games are fine with integrated graphics, or don't understand / care about the difference discrete graphics would make. If all you're doing is browsing the web, email, Facebook, chat apps, etc, a dedicated GPU probably isn't worth it for most people. This might be changing as more non-games utilize GPU compute power, but integrated graphics are also getting somewhat more powerful as compared to entry-level discrete GPUs. If anyone has a good comparison for this change over time, that'd be interesting to see.
