Welcome to MR, southpawflies!
I have the 505
*BLUE* and love it (it goes everywhere with me).
There are lots of free ebooks (see blue bar up above) beautifully hand-formatted by the members on MR.
Places to check out:
Writers' Corner,
Deals, Freebies, and Resources ,
Reading Recommendations, and check out the
MR Wiki for lots of information (even about checking out and reading library books on your 505).
Jump in with any questions you have and let us know what you like to read (we are a curious bunch on MR
)
