More than likely this was designed for the people who had 1200's that did not come with the internal hd and who are terrified of the tools(read: screwdriver) it takes to disassemble a 1200 to install one. I wouldn't call it technology, its a simple add on.
the A1200 IDE is terrible/slow,so who knows if this was a faster solution-Likely not since pcmcia is 16bit and quite slow.
