Ah. No, I'm not Michael Mace, I just agree with him about wanting an infopad.
Regarding "Of Mist, Grass and Sand," that was the novella (took either the Hugo or the Nebula that year, I've forgotten which) that was later expanded into
Dreamsnake. I've read both.
Dreamsnake is an old favorite of mine, so I was quite excited at the idea that there might be a sequel.
Most of what I like best isn't available as (legal) ebooks yet, but you might try Patricia Briggs, particularly the trilogy beginning with
Moon Called, which is available at Fictionwise. I'd also recommend anything by James H. Schmitz, and happily those are all available from Baen.
The closest to a long series that I'm currently enjoying are the Dragaera books of
Steven Brust. Especially recommended for Zelazny fans. (Or, in some cases, Dumas fans.
) Brust is currently looking into making his books available as ebooks.
