just been thinking....allot of people are stressing over selling their DX/DXG units because they're no longer supported.  the only option is to drop down to a 6 inch screen which is impractical for pdfs.
my decision is now to wait until the inevitable magazine style colour eink devices appear in a year or so.  there's already some 9.7 inch colour units appearing in academic markets in russia and the US.
i imagine the next iteration of colour eink technology will wipe the slate clean again but how long will it take?  my estimate is possibly 2 years from now.  hopefully my DXG lasts that long 
what do others think?
