You can run AE on a netbook if you wanted. You do lose some screen real estate, but that's mainly the info on the very bottom which on the netbooks I have used for it are VIN, make, model, engine etc non-essential unless you are a shop.

Everything that you have listed so far is done by AE and a few other things that you haven't listed yet.

They did have it to where you could use a a PDA to read everything, but their enhanced features got so big and intensive those devices couldn't handle anything above the generic powertrain anymore.

I had considered using a PDA for that since I had one. Also depending on what PIDs you are running at a time, it might be better to use a device that has quicker processing time then those handhelds that I saw a picture of.
