Will 13" 1.86 4GB new MBA run Aperture 3?

[iphone3g28]

I am selling my 15" 2.53 4gb MBP because of the form factor with the 13" MBA, but am curious how well the 13" 1.86 4GB MBA will run Aperture 3. Will I notice much difference when editing in RAW, or high MP (15) jpeg's?

Thanks for any input.

Edit: I also own a 21.5" i3 iMac, which I do most of my photo work on, am just wanting something for light editing and to transfer photos on to in the field.

I'm sure it will be fine.

I have a Rev B MBA with the 1.83GHz processor (only 2GB RAM though). It ran Aperture fine, although many adjustments were jumpy. Still usable though. Yours has a better GPU and more RAM so I imagine it'll fare much better.
