There are now 8 Gig SD cards on the market, called HDSC. Even better, you can get them with a BUILT IN USB connector on the other end. One end has the SD pin contacts, the other end has USB port contacts that are hidden away under a folding plastic flap.
The only trick is getting the Treo 700p to see all 8 Gigs.
Amazon has both the 8 Gig and 4 Gig convertible SD/HDSC/USB cards. The 8 Gig one needs the hack, the 4 gig one doesn't!
4 Gig (no hack): http://www.amazon.com/SanDisk-SDSDPH-004G-A11-15MB-Ultra-Plus/dp/B000UZJ0O2
8 Gig (needs hack): http://www.amazon.com/SanDisk-SDSDPH-008G-A11-15MB-Ultra-Plus/dp/B0012W7HGA
This guy has pretty good instructions.

In case his blog goes away, here's the 2 key links, but READ HIS INSTRUCTIONS!!!

Both files are free, and you do not need to even register, pick "download as guest" if you're in a hurry.
The only weird thing is that Palm reports either no memory available, or negative memory available, but applications still seem to work. The camera and a few of my favorite games still seem to run correctly. The camera now reports 7000+ available pictures. I'm now at a bit over 5 Gigs (copied over some test files)
So, you have a Palm with 8 Gigs of memory.
AND, if you get the dual connector style card, you also have an 8 Gig USB Thumb Drive with you at all times! Pop it out of the phone, crack the hinge, and pop it into your favorite USB port. Move files over, pull out, fold back flat, and back into the Palm.
With that much space, I wondering if these SanDisk Ultra II Plus cards would boot a PC? Modern PC's can boot from external drives on USB ports. *Some* USB thumb drives will also work... though some don't.
So in addition to having an 8 Gig Palm and 8 Gig thumb drive, you could also potentially have one of those portal virtual Linux boxes with all the portal apps. Walk up to somebody's computer, pop a chip out of your phone plug it into their computer, reboot, and your phone's memory card is now running Linux on their machine. Pretty cool, though I have NOT tried this yet.
We're livin' in the future.. future... future.....
Update Mon 5/12/08: Somehow the Treo no longer recognizes the card, it offers to format it when I insert it, but then it gives an error if I say yes. Inserting it into the PC with the USB end shows the files are still there, looking fine.
I'm not sure of the cause. I did move the card a bunch of times between PC and Treo. And I had accidentally downloaded an Audible title to the phone's internal memory because the card wasn't in there.
When I have time I'll try adding the PRC file again, etc. But this is a bit unsettling. At least the data is still there.
