Brighthand: Why some PDAs will not get Windows Mobile 5

Brighthand takes a look at why some PDAs will be upgradeable to Windows Mobile 5 and why others will not. Much of the explanation has to do with persistent memory.

To address this issue, Microsoft has reworked how memory will be used in Windows Mobile 5.
