[2]Yes, you had a slider that could control how much ram was allocated to running programs and how much to storing them. Except if you went too far from 50/50, it would forget your setting. 2003 ran fine on any device; upgrade to 5 or later, and it ran much slower.   I used to assume that those sort of devices had no flash whatsoever and the only options for storage were volatile memory, a ROM chip, or magnetic media. Palm OS did it too, I had a Tungsten I loved that the battery died on. Yeah, it was probably something like that. Unfortunately, like I said, the 4705--as well as the 2000 series, and I'd heard most other devices that had 2003->5 upgrades--ran like shit when upgraded. Some kind of algorithmic change I can't remember, perhaps GC, ran MUCH more frequently and aggressively, and would basically lock your machine for 5-10 seconds once a minute. People spent ages trying to find mitigations, but i don't think the issue was ever fixed per se. People whine about Windows upgrades ruining their experience by changing the way stuff works or removing features, but most of the Windows changes don't render your PC literally semi-unusable. Ah, found it: http://blogs.msdn.com/b/windowsmobile/archive/2006/06/07/621132.aspx not quite GC, but erasing dirty flash sectors. The problem was more widespread than he claims, and really nasty. ETA formatting. My Symbol MC50 didn't have that problem when upgraded from PPC2003 to WM5.0.  Maybe Symbol actually did testing or something.
