It will be interesting to see what a dual-core mobile processor can do with the extra wiggle room.
Well, my Droid (with overclocking, compcache and other tweaks) strains to run 24+ widgets and the equivalent of 12 or so homescreens....
So 4 times the ram and a dual-core should easily handle twice my current home set-up. I could add another 5 screens with stock/portfolio widgets.. muahahahhaa
