Love the TiBook I bought one new back when I was at Uni and I still own it - I flew it to NYC with me once on my 21st birthday (now so long ago!). Cosmetically it's a bit rough around the edges but generally it's OK. 

Always seem to run hot for my liking but recently I got her up and running again as I found a copy of Myst Exile collectors edition in an old cupboard someone was clearing out.

Good luck getting it running sweetly! Best looking powerbook of the series to me.
