ever since you lucky bestardos got the new update(i.e. multi touch) so ya I want to trade my 16gb 3gs......but I know....if I were you id have a cold dead grip on my nexus one, I might have to ebay it!!
I am up to 160mb of space used and have 82 apps in my app drawer (not including widgets I guess). I don't use 75% of them, at least. I even deleted about 5 yesterday. I can't imagine you having about 120 apps and using them regularly.
The only reason I would ike to see an app2sd program is to place the apps on there that I don't use more than 1 time a week or month.
