It's advancing just as fast as ever... Moore's law is still going strong, although you may not notice it quite so much on account of the fact that a lot of devices have been shrinking in recent years since for the average user, things have gotten fast enough and to hold enough data.
But in 6 years, we'll be talking about how new machines can get 1TB of RAM (although I'm a bit doubtful that dedicated computers like the MacPro will still be around in 6 years. Sooner or later I expect we'll be replacing them all with dummy terminals resembling the iPad and just use cloud computing for number crunching.)
