Yeah I think this is a good move for me, space wise. I have sold most of my desktop machines and moved into PowerBooks, takes less space!
Right now got my PB100 as it's the oldest/smallest, then a 540c as it was the most powerful non PPC, a 2300c as it's the thinnest and now the 180c as it's the nicest colour model for that form factor.
Btw, I want to get rid of the pb100, 140, 170 parts I have. Would like to swap for something, anyone interested? I'm in Richmond UK.
