| 1993 | PB140 | The Dynabook was exchanged with PB140. Squirish, dense, and heavy powerbook charmed me a lot. |
| 1994 | Quadra650 | II si became outdated soon. Q650 with PowerPC card was very excellent but the life was short. |
| 1994 | LC475 | Slow, small RAM, and small HDD but the price is so cute to allow my household to add 17" apple monitor. |
| 1995 | 8100/100 | Kobe earthquake brought tremendous amount of research budget, just a smallest portion of which brought a 8100. |

| 1999 | MG DoCoMo | A little faster MobileGear communicating with NTT cellular phone. E-mail everywhere. |
| 1999 | INSPIRON3500 | Urgent need for GMT and ArcView forced me to buy Window98 CPU. It's not too bad, but fast. Good job. TASTELESS Windows are HORRIBLE. |
| 2000 | G4/400 | Skipping G3, G4 is wonderful. Dual display of 15"LC and 21" using ATI Xclaim VR 128. |

| 2001 | PBG4/500 | Thanks to a kind friend of mine, I got this for FREE! How nice to use GMT in OSX and to get rid of tastless Windows. Very stable and reliable except for bottom case. 200,000 mile flier. |

| 2005 | PBG4/1.67G | No trouble until June 2008 except for memory slot problem. Very durable and hard-working. Accompanying all 300+ flights over 300,000 miles. Never without you. |
