Liz,

I would go for the Dell as it has more disc space, otherwise their much the same.

One thing I did read the other day is that the way Vista 32 is set up, it cannot use the full 4Gb of memory so your not gaining anything there. 3Gb is more than adequate for photo editing.

Many of the apps will not be able to make use of the Vista 64 bit features and some may not work.
