Late model Titaniums

[Alarik W. Skarstrom]

Dear Titanium List,

I am thinking about buying a late model Titanium PowerBook. By late, 
I mean after it acquired the Level 3 cache. There were, I gather from 
the reviews, many improvements over the earlier models (in terms of 
screen quality, bus speed, etc.).

My question is this, well, two really: Aside from its hinges, does 
the later Titanium have any other Achilles' heels?

The company RadTech makes a kit for aligning the hinges so that they 
don't bind and don't, I assume, break. Does anyone have any 
experience with this?

Thanks!

Alarik
