iBook

“Since I bought my first Mac in 2004 (a 12" iBook G4), I've always traded-up aggressively to each new model on the theory that a Mac's resale value is usually high enough that the marginal cost of each new machine is relatively low—especially for a device that I'll often use for 10 or more hours a day.”

“For writing, I have a 2001 G3 iBook with a 500mhz PowerPC processor, 128mb RAM, and a third-party battery that just never dies.”

“I had an epiphany about 8 years ago, when my home office went from having 4 big tower PCs in various states of repair and OS, along with my own servers and NAS and lots of cable runs and so on, to a single iBook running off Wifi.”
