Also, as Ferdzy mentioned, even when you use fabric bags, you still end up with some number of plastic bags. We'll hoard those for non-recyclable household trash and dog pick-up.
I also have my beloved iPAQ handheld, not exactly practical for classroom notetaking. Allan uses a laptop, which I can use when we travel, so I've never needed one of my own.
Not knowing if notetaking will work out for me, I didn't want (and really can't afford) to buy a good new notebook, plus I need something very light because of issues with my joints. I posted a "wanted to buy" ad on Craigslist, yadda yadda yadda, yesterday I bought a ThinkPad in great condition, including a new wireless card, for $230. It's so nice and compact. I removed the battery, which I'll never use, to make it even lighter.
I thought I would pick up a wireless mouse, since I've never used a TrackPoint and assumed I would find it difficult. I'm useless with a touchpad, and I assumed the TrackPoint would be similarly difficult. To my surprise, I'm getting accustomed to it very quickly. I think soon I will actually prefer it.
Let's see... do I owe you updates on anything else?
