While looking about for an 8GB microSD card for my new TyTn II, i stumbled across this:

microSD to MS PRO DUO Adapter (for MS PRO DUO devices) : MobyMemory Card Adapters

Genious!

An 8GB duo card is a good £20 - £30 more expensive than microSD cards. If i wasn't leaving abandoning all my Sony/SonyEricsson gear i would probably get one.

The same place also has a really tiny microSD USB reader.

#TINY Micro-SD USB 2.0 Memory card reader : MobyMemory Card Readers

Smaller than most pen drives.
