I'm really not sure you could or should replace a pc with an eDGe. The Android os isn't made for heavy computing. It's only a smart phone os, after all.

I didn't see reading pdf or epub books, manuals, etc on your list. This is a big part of the eDGe, along with annotating those files. Doing such things as surfing the net, the eDGe is good, but probably not better than (or even quite as good as) a netbook, tablet or other pc. I prefer the pc for typing.

Others will chime in, I'm sure .
