I use Textmaker, PlanMaker, and ListPro (with several ~ 1 MB databases). Textmaker & PlanMaker take a relatively long time to load/run when stored in FLASH ROM (or even an SD card) than RAM.
One of the benefits of the Windows Mobile development platform to a developer is the high degree of standardization we try to keep. Persistent store is a great example of such a technology, rather than making it optional for OEMs we have standardized Windows Mobile devices around it. The net of this is that longer term, developers can optimize to things to persistent store and be confident those optimizations are applicable to all in market devices. I'm confident over time apps like ListPro, PlanMaker etc will be optimized for persistent store and not suffer long load times.
An example of this type of optimization is the UU Encode and UU Decode algorithm in Outlook Mobile which initially ran very slowly. We discovered that it was reading the blocks to decode 3 bytes at a time from the file. Because file reads are somewhat slower by simply buffering the read we were able to achieve better performance.

Something that greatly concerns me, and should concern most corporate users, is that if my pocket PC should ever all into the wrong hands, I?m secure in the knowledge that when someone does a hard-reset, all of my data will be gone. Please, someone correct me if I?m wrong, but if this should happen with WM5, after someone did a hard-reset to gain access to my device, my sensitive data would still be there for them to use. Even if I encrypt my data, they still have something to hack. Am I wrong? (I really hope so).
A hard reset is still a hard reset. It will flush the file system and registry so your data would be wiped off the device.

I want to buy an Axim X50v. When I get the WM 5.0 upgrade in October, will that transform the device into a persistant storage device, or is that a hardware thing where I have to wait for a new device that has the proper hardware in it to have persistant storage?

No, all Windows Mobile 5.0 devices will be equiped with the persistent storage feature, so as soon as you apply the upgrade to your X50v, you're geared up with the new storage technology.

After reading many..many posts about WM 2005 persistant storage of people who know very well what they are talking about I still don't know what to do because a lot i've read was to "technical".
I'm in the proces of buying another VGA PPC. With WM2005 around the corner what is the better choice when it comes to memory setup:
128 Mb RAM and 64 Mb ROM (Loox 720)
or
64 Mb RAM and 128 Mb ROM (Dell X50v)
When looked at purely from a memory point of view, the Dell setup is good, as having only 64MB RAM will lead to less battery drain, and 64Mb ram should be enough for most people. The 128Mb ROM should mean you can install more on the device directly, vs installing apps on a SD or CF card.
Its however less clear cut than that, because
a) the loox has a much bigger battery than the Axim (1640 vs 1100 mAh), so the slight increased battery drain is negated easily. In battery stress tests the Loox lasts longer than the Dell, despite the bigger drain from the battery, and it will continue to do so.
b) the 64MB extra ROM that the Axim has can be slower than a fast SD for installing apps, and 64 Mb SD cards are basically free.
c) In some extreme situations the 64Mb extra ram could come in very handy. If you have it you will be glad, if you don't you will be stuck. The same can not be said of an extra 64MB ROM.
d) The Loox has a number of other great advantages such as USB host, VOIP speaker, jog dial and better screen which is much more important that how the memory setup will change in WM 5.0 . Of course the Axim has a slightly faster processor (520 vs 624Mhz) and a very good 16Mb video accelerator which is getting increasing support from developers, and in America is MUCH cheaper.
In summary then, the memory changes are interesting, but not as important as the other issues as cost, support and features.
Dunno if this quote has been discussed in the thread or not (don't have time to check it):
"A typical battery holds 1000mAh of charge. 128M of RAM takes about 500mAh to stay resident for 72 hours. 64M takes about 250. This is why you never saw a 256M WM 2003 device. It would have run for a minute then decided its batteries were critically low.” – He added."
This may have been true with early, third-party memory add-ons (for example, the iPAQ 3630 with an additional 32M RAM), but not with today's high-end 128M RAM PDA's.
For example, the Pocket Loox 720 (a 128M RAM device) only consumes some 100 mAh a day when suspended (this has been reported by several PL720 users). This means you can leave it unattended for even 2 weeks.
