I think i need some advice from our Professional OS cloners.
I have a 4gb SD and a 8gb SD (that I received today)

I want to be able to boot from one of my SD and also have KDE on that same SD.

Do you think I have enough space on my 4gb to do so, thus leaving my 8gb solely for Media ?
Or should I clone the OS and KDE on my 8gb ?

Thanks in advance (and also after replies )
