Hello all... well I bought it last night and Im already loading SPB software.

....
The main question is when I add a memory card will it act as root memory (For lack of a better term, will it get added to the C: drive) or does it create a new partition (D: drive or something)? I know Im using PC terms but Im just trying to put it in terms I can understand.
Im asking because I started installing programs and I was wondering if I should wait till I get the mem card... Im also concerned on where "My Documents" will sit and if I will have to move it to a new partition. If it does act as extended memory how hard is it to upgrade later?
SPB software seems to be really nice but I have a problem understanding their packages... do any of them over lap, i.e. have the same features or should I get each package for particular features?
Sorry for the questions but I did some searching and couldn’t find what I was looking for.
