I have an iBook - I always liked the look of the thing when it came out and around 2005 when it was no longer the current model, I bought a grey&white 366mhz, 10gb HDD iBook and the matching curve-shaped bag via eBay
Its had intermittent periods of use as and when I needed an extra machine, and although now 14 years old, with RAM upgraded to 392mb, an aftermarket battery giving 7 hours on a charge and OSX 10.3.9 installed, it still works. HOWEVER - it has an original Apple Airport card (probably worth more than the laptop & bag put together...) and these dont work with WPA2 or with any 802.11n router - they just wont connect.
So its just become a curiosity on the shelf - a machine with only one USB port is hopelessly compromised by using an external Wifi adapter.
