Separated by 16 years of “courageous” Apple innovation, on the left is the model of laptop that got me through college, particularly used in Unix class, a bit of socket tomfoolery in Networking class and for note taking in everything else–and it played UT99 and 04 just fine–the iBook G3. On the right is the new hotness, the 2018 MacBook Air. Entry level sure does look a little sleeker these days 😉
