User Feedback :: Pendrive as a disk

From my (sth one day) short study od DSL pendrive distro I have a question....

Why DSL uses pendrive only as a Live CD? Why it cannot take full adventage of pendrive and use it as a hard drive (without that silly saving/restoring and loosing 'saved' data)?
Making my dreams come true would be a pendrive which converts my box into a linux machine, not another Live CD demo.

Thanks for the answers.

Because pendrives like any other flash memory devices have a limited numer of writes before they fail. Flash memory does not equate to a real hard drive.

What about ability of writing all the stuf automaticly once during the system halting?

So you cannot backup files to the pendrive you are using as a LiveCD? If this is the case It does seem silly to use DSL as a portable OS.

ofcorse I can (isn't it a Linux is all about

but for now on I don't know what files. For example, If I add some new package, how to make sure it'l be back there after reboot.....can it be "automatized" in some future versions of distro?

Can we consider using small 2,5'' HDD in USB-connected socket? Then we have mobility of USB device and 'unlimited' count of saves...
