Hmmm...SSD?
Mal, I'm not kidding, that no-name, made in China, acquired at some Microsoft tech summit USB headset actually works. Haven't tried the microphone yet, though. The earpiece works well, though I would imagine it won't do wonders for battery life.
Too bad the Touch Pro doesn't have that. It's pretty cool to be able to read/write a USB stick on your mobile phone.
