The AlphaSmart Neo is a full-sized keyboard with a little LCD screen on the top. It acts as a word-processor, letting you type into its 512k cache while it draws power from 3 AA batteries. When you get back to your Mac or PC, you just dump the text over USB or IR. The thing runs for 700 hours on a 3 AA batts and costs $250, and weighs about 2 lbs.
My only complaint about this thing is the storage: 512k? I know that's a whole novel and then some, but geez, flash-RAM is so cheap now — why not just give it a SD slot and I could use an old 64MB card from my last camera?

Update: Chris Taylor points out that AlphaSmart has a model that supports memory cards — and it comes with WiFi and PalmOS.
