Completely untouched? What are you supposed to gain by doing this?
I have moved everything possible to SD card, and I've still about 3rd of the internal memory free. I don't use a lot of widgets, so losing the widget functionality that has not concerned me. I keep my phone clean & organized but I think generally I have more apps than I really need.
I have not rooted (yet), but getting rid off some of the stock apps would obviously free couple of dozen megabytes at least.
All apps are not installed on the internal memory by default (unless there's a setting for this), but most of them probably.
