I use my HP Pavilion laptop as my desktop computer, and have it hooked up to some speakers, so naturally I'd hate to have to unhook it all and carry the laptop to college, in addition to lugging it back on my trips home.

So I bought a netbook to use primarily for browsing online and writing documents out of my desk chair; due to my disability, I get a lot of backache from sitting, and a bed is often more comfortable.

Furthermore...and having all these devices makes me feel so guilty, but I pay with money I make selling online as well as social security/assistance checks...I purchased an Edge so I could more comfortably read books in bed as well as browse online when certain passages interest me, and markup the text without ruining my pages.

My question is, given my reasons for having a laptop (a few years old, bought new) a netbook (refurbished; paying $200 for it shipped.) and a $508 shipped e-reader/lite netbook, are these purchases justified, in your opinions; or should I simply cancel my netbook bid and buy a USB keyboard?
