Crosley Revolution turntable
While we are on the topic of the different formats our music can come in, this is a great example of the revival of an old one. The Crosley portable Revolution turntable seems to be designed for people who still have some vinyl record but do not have the space for a full size turntable.
I found this nice and compact battery powered machine via Retro Thing, and as they conclude, its form factor is almost identical to the Audio Technica AT-727 'Sound Burger'. It looks great, but the record is unprotected and it will not replace your iPod as it is hard to fit one (including record) in you pocket.
