If you had to pick from Sony's smallest form factors, which is your favorite? 

To the best of my knowledge, that includes the WM-10/F10, WM-20/F20, WM-30, WM-10X, WM-20X and ???

My first Sony, circle 86/87 (in a trade for an apple 2 disk drive) was for a blue trim WM-10 (sans battery cover- told handle it was to constantly secure the battery by wadded paper, gum, thumb, etc). I played the heck out of Run-DMC 'Raising Hell' and Kraftwerk 'Electric Cafe'.

I'm sure I'd have been majorly jealous of the WM-30 or WM-F10. But now that I have a mint working WM-F202, I'm in love with that. 

Another good question is- did any other company's cassette deck get that small? I love, love AIWA, but the lost the size game, IMHO. I didn't have the faculties to consider the sound quality, probably don't know.
