I think this is probably my favorite model (next to the Tangerine one for sentimental reasons (it was my first laptop)).
I'm glad yours was cheap. For some reason, they're hard to find (at least in the US), and expensive when found, so I overpaid quite alot for my collection. Another thing is that the Indigo (which yours is), is hard to find in good cosmetic condition. Every one I've come across has had some unsightly fading of the rubber from a deep blue to a kind of greyed out blue-ish color. Yours looks to be in decent condition, fortunately.
Anyway, I hope you enjoy it!!
