They are talking here about 16MB compact flash.
1GB is pretty cheap Compact Flash, SD.
Many PDA's are getting USB host. Most big 20GB+ MP3 players also work as external hard drives. Brighthand listed a must have PDA feature list, 20GB+ drives came in 11th with 64% wanting them. Hopefully someone might write the mass storage device driver.
After a look there is a beta for the driver here.
When I installed the software it asked if I wanted to replace usbmsc.dll. Having read the problems and this was just a trial I said no. I then read the 4 page instruction leaflet with my newest PDA I thought might do USB host. It said it does mice and thumbdrives. I then had a laugh with imagemaker and a mouse when you can't see the pointer. USB mass storage it didn't want to know, maybe the driver worked, more likely I'd of lost essential mouse input to my mobile phone.
I'll have to include show pointer in my programs now.
Anyway then I stand by what I said. Once the drivers are sorted out connect the Ipod and transfer what you need to a 1GB card.
