The SE is about the most useful desktop 68000 Macintosh. It supports ADB, some internal expansion options, internal HDD and 2 internal floppies (both with the right kind of HDD), external floppy port, ADB ... the list goes on. It's a bit noisier than the Plus, and not as fast as a Portable or PB100, but it has its plusses. Especially when you want to run old Mac software that has "issues" with newer (32-bit) equipment.
