This is just using a digital solution to an analog problem for no real gain in efficiency. In theoryland sure, you can replace books with ereaders and possibly save money. And at certain levels of education this works out, middle/high school. In earlier levels, there are two issues. One, kids break things. Cheaper to replace a book than an ereader. Two, kids associate the tablet form factor with entertainment. Kids rely a lot on symbols for interpreting the world. It’s hard to get them into education mode when the symbol on front of them puts them into entertainment mode. Books signify learning, it helps the kids get into the right headspace.
Very happy with it. $400 MSRP feels right, I don’t think I would feel so positively if it was more. I’m on vacation right now and using it a lot to wind down in the evenings.
