Both are mostly closed with pcmcia/cf/sd slot... And, whoops, USB ... which lets systems expand easily. If the device supports a hub, then you (or, more accurately, crazy people!) could add over a hundred devices. That's pretty "open". AFAICT the hardware folk are more than ready to start providing hand-held devices (PDA-ish, vs luggable laptops) with USB host capabilities. But WinCE isn't ready for that yet though... ergo products don't do it yet. Linux has less trouble, since market positioning doesn't interfere. :) - Dave
