My brother got new 12" iBook (1,2Ghz) with combo drive and 512MB of RAM, but he more likes my Ti.Most of time he surfs internet at home.Plugged in all the time. Is it worth to trade 500MHz G4 Ti with airport,640MB RAM,DVD-ROM and dead battery or buy a combodrive upgrade and new battery ? Most of time I work in Xcode,Safari and shell.
