Welcome to MobileRead, Lov3Read!
You can find out lots about folks experiences with clip on lights and the Reader, in the
Reader Accessories forum, the latest discussion thread is
here, but there are other threads on the topic too.
There were some rumors about a 'next model' but that was 5 months ago, with nary a hint of a peep since. I haven't been able to dig up with anything that would indicate any work on a version next, so my guess is that if they are, it must bee in the early concept stage, and we wouldn't see it for at least another year or so.
And you can salt that to suit your taste.
