Any of you who saw my previous post on the release of Microsoft's Windows Mobile 5.0, and are concerned about the performance, reliability or other potential impacts of the migration from DRAM to flash memory exemplified by the Persistent Storage feature, will likely be interested in a series of blog posts by Microsoft employee Mike Calligaro. The original post is titled 'Why Persistent Storage Is A Good Thing'. The followup, 'More Persistent Storage Stuff', is a two-parter; here's part 1 and here's part 2. Also, you might want to check out a vigorous discussion on the topic over at Pocket PC Thoughts.
