Kaisa Tarasov writes "It turns out PalmOne's new Treo 650 is shipping with a major problem that's causing first adopter users and developers to cancel their orders in droves. The new Treo, along with the Tungsten T5, utilizes a new FAT based nonvolatile file system. Not only is the new system much slower, as the data has to be loaded into a SDRAM chip before running, but in this filesystem PalmOne switched from using directly addressable storage, to storage addressed in 512 Byte blocks. This has caused many files to swell in size - up to 500% in some cases (such as the address book). Users, already flustered with the small 23 MB of available memory, when trying to sync their old data onto the new device are discovering that their old data does not fit on the new Treo. What does PalmOne do?"
