Sharp has again updated their hot SL-series. This latest version, the SL-C860, share the same hardware as the SL-C760 but has one new feature. Now, the Zaurus itself, as well as its SD and CF slots, will now be recognized as a hard drive under Windows. (The same way a memory card would be.) This new feature facilitates easier data transfer.
