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.
Same here. I had this futile attempt at running Linux on the desktop which was a perpetual cause of pain and frustration. I still love that first 12″ iBook that saved me from it all.
Now to get that iPad (I am a total InstaPaper fiend).
