Take Away:
First part which interested me is the battery design, comparing with present sealed battery. One of the most notable design choices in the iBook G4 was its battery. Apple created “coin lock”, removable unit that blended into the curved base. This decision was both practical and aesthetic. At a time when mobile use often exceeded a single charge, users could easily replace the battery without tools. Instead of keepping the high capacity battery inside with all the boards and components, this design would avoid hurting other crucial parts when the battery was damaged.
Another important feature was the keyboard. The iBook G4 used a full-sized layout with wider spacing and a large palm rest which integrated with authentic ergnomic considers. For the similar reason that this keyboard was also design as easyily replacable tool. No need to fix it in a complex way, it could easily operate by our own. Thus, these are the two components that interested me the most.
