I have found the Imation Atom to be very reliable and also very compact (I have the 4GB version).
Although the surface is a little scratched it is attached to a bunch of keys so I would be surprised if it were otherwise! Otherwise the physical durability has been fine. The drive is so small I feel the only real risk is losing it, and I would question whether I needed to buy one so small - as standard drives are usually no longer than keys.
The access speeds are fast - I sync with My Documents (over 1GB) every day using Microsoft's SyncToy (for XP).
I haven't used the secure partitioning feature yet but the software is included on the drive.
Overall, very satisfied.
