C700 Is Unstable And Slow Options

[gepeto]

I own a C700 with a 2gig SD card in it, and a Symbol wireless CF card that is pretty often in it.

I use OZ/Opie, and I usually always have the latest release candidate available.

No matter what, my C700 is always very slow and very unstable.
I cannot browse the web at all using the web browser, it is way too slow and eventually crashes.
I tried putting the SD in and creating a swap file, but it does not seem to help much.

The package manager also seems to hang all the time, especially when I try to install packages (to SD or not, does not seem to make a difference).

Is this common with the c700, because of a lack of ram maybe?
Or is it plausible that my unit is defective? If so, is there some application I can use to try and test the memory in the unit or something?

What should I try? I would love to use my Zaurus for work but right now I spend much more time rebooting it, then fscking the SD card because the Z crashed without unmounting it cleanly than using it..
