To me, it'd seem like the latter is just a waste of money, but I want to make sure.
Buying "2 GB dual channel (2x1)" is not different from buying two 1GB sticks. The 2GB dual channel you are referring to would be 2 1GB sticks (1 for each channel)...this would be the case when you want dual channel performance which only works if the sticks have the exact same specifications. Buying two one gig sticks separately could be a waste of time if they aren't matched correctly.
