Judy's slightly more than 2 years now. Working fine, most of the time anyway. Ran a PI calculation program just now, to test her speed. Took her 1m 46s to get to 2 million digits. For comparison, i got that off a website.

Acer Aspire 1692WLMi (1.73GHz Alviso Pentium M) 1m 49s
Gateway 7422GX (AMD 2.4GHz) 2m 12s
Dell Latitude D410 (2.00 GHz Alviso Pentium M) 1m 36s
IBM ThinkPad T43 (1.86 GHz Alviso Pentium M) 1m 45s
Fujitsu LifeBook N3510 (1.73 GHz Alviso Pentium M) 1m 48s
IBM ThinkPad T41 (1.6GHz Banias Pentium M) 2m 23s
Compaq R3000T (Celeron 2.8GHz) 3m 3s
Dell Inspiron 600m (1.6 GHz Dothan Pentium M) 2m 10s
Dell Inspiron 8600 (1.7GHz Banias Pentium M) 2m 28s

It may not be fair though. I don't know how many processes each of those machines are running. But i did close PG2, Messenger, Firefox & Notebook Hardware Control. Without closing, i got a 1m 51s.

Battery wear level at 76%, just a slight increase from a few months back. I'd say not too bad.
