Caroline had a pet peeve for some time: because CJ found our oldest iBook (500MHz G3) too slow, he often borrowed her 1GHz G4 iBook to play games that were too taxing for his iBook — it was fine for Zoombinis Island Adventure or Putt Putt Goes to the Zoo, but not for Tribal Trouble, Enigmo 2, or Ottomatic. Caroline finally decided to upgrade — to a 15-inch MacBook Pro Core 2 Duo, the 2.16GHz model with 1GB RAM and 120GB hard drive. So now she has the fastest notebook in the house, and I'm soldiering on with a 3+year old 800MHz iBook G4. CJ inherited her iBook, so I have the slowest notebook computer of almost anyone I know. I'll hold out until MacOS X Leopard ships before I upgrade. But I'm so used to my iBook by now, I think I'll miss it in the sort of way that one misses a comfortable pair of old shoes, or a favourite shirt.
Update: As part of Caroline's Christmas present, I bought a 1GB DDR2 SO-DIMM and put it in her new notebook, so now she has 2GB RAM. And she complains there are no games on it... argghh. :-)
