This image purporting to be the current concept design for 3M's upcoming ereader looks awfully familiar. In fact, the similarities to the txtr reader we saw a couple of years back are pretty uncanny -- and they're likely more than skin deep, seeing as how 3M has been investing in the company. There's a decent chance, however, that the device will hit the market looking a bit different -- and hopefully with a few other changes on-board, since the txtr reader is now a bit ancient. One thing does seem fairly likely: the device will probably play nicely with 3M's recently announced Cloud Library lending service. You didn't expect 3M to let other companies have all the fun, did you?
