The log scale is nice to compare decades. Wether it's inflation-adjusted or not isn't too important but it's still a factor of 10, which would show in a linear recent graph. The fact that we're comparing GBs instead of the average RAM stick shows how much the price has decreased per GB rather than per unit (much smaller decrease). But a linear graph that represents only the last decade and where the bottom is 0 (not the min value) would tell a different story, but I guess we already know that story because we're living it.
