I have the HTC Evo, an HP laptop 1yr old, a refurb Gateway laptop-2yrs old, and the eDGe. I have definitely used the eDGe for reading articles and classwork while annotating, the journal app is great for writing down notes, and the eDGe is hella light compared to my 17' HP so i carry it around when i know I'm going somewhere and will have time on my hands (e.g., doctor's office, meeting, conference, etc.) to read and take notes. An eDGe + an Android phone can easily replace a netbook especially if you have swype and add an HDMI cord and an external HDD and you won't need a desktop or have need for another screen if you hook it up to your tv. I think a netbook is unnecessary with all the devices you have OP.
