Well, it depends on why you want it. If you want it to play a few games that you fondly remember, then yeah, get it. As theclaw pointed out, I don't think there will ever be an emulator for it. I've never even heard mention of one and I stay pretty up-to-date on the emu scene.
If you want it for a collector's item, then it might not be a horrible idea if you can get one for cheap. I only see like 18 of them on fleaBay which is a pretty low number. They seem to be going for around $50 or more also.
It will probably be hard to get many games for it also.
