Primary data storage should always be on your pc(s). That is the most convienent and easy place to use it...
Setup a linux box with four matched SATA drives (e.g. 300GB) setup as a large striped drive. Most modern motherboards will handle this without problems.
Use backuppc to backup your pc(s) (linux, windows, mac, anything that runs SMB or rsync) to the large striped drive.
You don't need RAID as the large stiped drive is just a backup copy. And (hopefully) won't crash with hardware problems at the same time as the drive in your pc(s).
For extra redundancy place it offsite somewhere and backup over your cable connection. Swap machines with a friend. Host his backup at your place, he has your's.. Then in case of disaster all of your data is still safe.
Cheap, simple and robust. Just setup, configure and ignore.
It will take a year or two for Linux on PDA's to become mainstream. And by that time the target device will probably have 2-4 times the processing power or 2-4 times the battery life (e.g. Xscale instead of ARM), 128-256MB RAM, 64-128MB Flash, hard disks, SD ethernet/wireless etc, etc.
At that point the devices look anemic running WinCE, are still too small for WinXP, but Linux is a very nice fit. You get a Posix compatible, open operating system, your choice of GUI's, tons of networking support.
These devices will also be less expensive when shipped without paying the Microsoft tax and therefore more competitive in the long run.

I implemented both spamassasin and ifile one month ago.
Results
Both: 787 62%
SpamAssasin only: 385 30%
Ifile only: 62 5%
Missed: 29 2%
False positives: 0 0%
I'm fairly happy with these results. I see about 1 spam message a day.
