If being a fan of Star Wars merchandise is more important than the actual functionality of those products, then the official lightsaber MP3 player could be just what you’re looking for.
Low on features (plays music in the order it’s stored on a memory card) but high in visual appeal, it’s 8cm (about 3 inches) in length and authentically detailed.
It should be, in fact, because it has been officially licensed by Taito. I’m sure you can get knockoff variants for less than the $23.90 being asked here — they might even have an LCD to view your music track details on. This one doesn’t, but then it worked for Apple so that shouldn’t bother you much.
OK, fair dos — you can’t use it as a real lightsaber. I bet you’re shocked to learn that.
Anyway, it’s been online for a couple of months but won’t be available until February. If you’re interested in pre-ordering it, head over to the Star Wars Light Saber Kei MP3 Player product page.
