As far as durability is concerned( I just toss them in my back pocket, w/o cap, they are sat on constantly, dropped, and used ) and I have gone though:

- 2 Corsair Voyagers within 6-8 months ( they end up turning into unrecognized device or bar device )
- 1 Kingston in 12 months ( casing broke, drive OK )
- 1 OCZ rally within 2 months ( usb device not detected )

Kingston has been the favorite, except for its cheap shell construction.

Very useful review :)
The only question that i have is:
When you gonna do 16 and 32 GB models ?
I want to by new one and with 32GB priced at +-150$ i do want big one. I want to put OS on it :)

Other thoughts:
I want to see 1394b stick.
The USB 2.0 can't do more then 270Mbp/s (34MBp/s).
So the current limit of performance sticks is USB interface.
Even FireWire 400 can do much better :)
