Great thread. I found this forum when looking for a similar answer when I started my PhD ~8 months ago. Been keeping an eye on all the progress since then.
At the moment I'm saving for a reader myself. Gonna aim for one of the iRex ones as reading pdf journals on it will be essential. I was going to try and go for the DR1000S but when I see the 2 of them side by side in cbills pictures it looks like a monster! I'd want to be reading normal books on it too to justify spending that much and it looks far to big to carry around comfortably.
I'm also hoping that some more choices will appear while I'm still saving
. Course there's always something better just around the corner....
