I have both a STacy and a Mac Portable, and they're not even in the same class. The Portable has a fabulous screen and a wonderful full-stroke keyboard, and feels solid and professional. The STacy feels cheap and thrown together. The Portable can be relatively easily worked on, the degenerating plastics notwithstanding; the STacy hides screws and flexed dangerously even when it was new.

But the STacy is an ST, and it's the only one I've got.
