This novel(la) had so much promise, an interesting concept and not worn out by too many similar ideas. Well constructed at the start, good background info and placement into the possibilities of the time it is set in. Just too short, it ended rather abruptly, maybe stringing out the reader for the next one, which as far as I know there is not. (bit Apple influenced by I-this I-that and I-the other terms - but also quite clever) It IMHO did not explore all the possibilities that the story line created, I don't want an upgrade is the elctronic whisper i hear from my computer every day. Well worth a read if you like this Genre, I have read it more than once.
