no.
personally i think this is stupid because i already paid to upgrade to lion for icloud and my comp runs slower for it, yet they want more for me to access my photo stream in a program i don't use.
imo it is a big leap they are asking people to take to completely turn over their photo library to a program that doesn't give access to individual files... i realize that is part of the apple aesthetic but at least having the option of a dropbox-style folder or the ability to sync/select/delete via itunes would be nice- i'm terrified of building up so many pictures that they become a tangled mess, so I basically don't take them.
on the other hand, maybe that is the point of photostream. for now i'm not shelling out any more money to use a feature that should have been built into the two operating systems i just paid for.
wah wah wah
