Yeah, a lot of the older Windows Mobile (mostly branded as Windows CE) pda only type devices used a single pool of volatile RAM as RAM AND storage. Who thought that this was a good idea needs to be stabbed, of course, but it's important to realise that this has no bearing on newer devices, using non-volatile flash for their storage.

Still, Windows Mobile has godawful fit and finish (a bit like their desktop operating systems) and it really pokes through at times, even when using HTC's excellent TouchFlo
