Checking out the D3 specs looks like (from most sources) that it will be checking in with 512 mb RAM. For those of you that have phones with 512 mb of RAM, (unlike me with a paltry 256 on the OG) do you find that 512 is enough? For me, I can usually get two apps switching at the same time, more than that and the app has been killed and has to restart. So I'd like to get a handle on how much seamless switching I can get with 512? I think those of you with the DX2 could offer the best opinion because your type of RAM is the same kind that will be going in the D3, but of course anyone with 512 who cares to weigh in is more than welcome.
