Used Palm Zire 31: $60. Thank you, craigslist.
Palm universal wireless keyboard from provantage.com: $48.48.
Result: something better and more compatible than the Alphasmart Neo for less than half the price. Take THAT, Alphasmart! I thought you were cheap, but your prices are clearly inflated. Look at my smart little back-lit cheapo computer with several MB of memory and more than 4 lines of text and an almost laptop-size keyboard. You are not as good as that. Weep for shame. WEEP!
