SPARCbook 3000ST: the coolest 90s laptop

A few weeks back I managed to pick up an incredibly rare laptop in immaculate condition for $50 on Kijiji: a Tadpole Technologies SPARCbook 3000ST from 1997 (it also came with two other working Pentium laptops from the 1990s). So, what makes this the coolest laptop of the 1990s? I used to long for a Tadpole SPARC laptop about 15 years ago, when they came with dual processor models. Amazing technology.
