XCM files used to be compressed but as of mid December are now just container files (think of it as a ZIP file which just holds files instead of compressing them - because that's exactly what it is.) This gives a performance gain at the cost of storage space. Hopefully all issues for users of old devices are gone now, in testing my iPAQ 3850 running Windows Mobile 2003 runs very well indeed with the UK data and memory use doesn't appear to be excessive. Extremely impressive considering there are numerous extra calculations going on in the background. The initial loading of topology from the SD card is slow though, these devices were notorious for sluggish memory card read time. As for even older devices, there were issues with PPC2000/2002 (2002 is basically 2000 with lipstick) performance which I think Max has fixed very recently.
