I wonder if that could be used in a very small portable mp3 player???

Per'aps...

I am also thinking about it for the silent computer aspect of things. Granted, 8GB is not that much by today's standards, but for a basic web surfing machine...

That would be good because it doesn't have any moving parts so there would be less chance of a hardware failure.

It would be usable in camera's that support 4GB flash cards because it has to be FAT32 (the whole 2GB FAT16 Limit). So only camera's that have FAT32 support would work.

Yeah. It's good and all but at an estimate price of $5999 each it's not going to be nice to the wallet! [edit]It's not the Lexar but somebody else has one and that's the $5999 one.[/edit]

I don't think that would be such a good idea. Well, the idea is good, but using compact flash cards for it is not. These cards wear off quite quickly because they can be written/rewritten only so many times. (and that number isn't *that* high). So when using them as a regular harddisk, the virtual memory would also be written onto that disk. I don't think any compact flashcard would last a lot longer than one month.
I don't know how the story is for those solid state harddisks, but I suspect they don't have that limitation. (would be pretty stupid if they did, no? )

If you were todo something like that, you'd be using the flash memory as a boot disk and everything would be getting loaded into RAM - so the flash disk would not be getting accessed afterwords at all.
Of course this would be easier done with linux the
Windows....but if you disabled the swap file (do-able if you've enough RAM) and pointed the internet cache towards a RAM drive maybe you could do it with 'doze and not batter the flash RAM.
But either way you would not need an 8gb card.
