This is a helpful thought. The T60 laptops are Socket M. Although the T60 I first tested SL7 on silently failed, it had a T2500 Core Duo processor, 32 bits. I just scrounged up a T7200 Core *2* Duo processor, 64 bits, and installed it in that T60. SL7 is installing on that machine now. I just ordered some allegedly new T7200s for $8 each, and those (plus spare complete laptops, and spare screens, fans, AC adapters, docking cradles, and keyboards) should last my wife and I until our brains shrivel. I'll occasionally test with the latest Fedora Live distro for early warning of future incompatibility. The T7600 is 16% faster, but 6x more expensive, and probably burns more power. The T7200 seems the lowest risk. The batteries will die soonest, but we should be able to get the old batteries refurbished with new cells (there are companies that do this for power tools). After that, electromigration of copper up through gold plating on connectors, then oxidation, will doom these machines. And who knows? After everyone has bought their wide screen (AKA vertically challenged) laptops, manufacturers will probably start pushing tall screens again. Or headmounts. Or brain implants. The current fad is bigger and bigger handhelds with asymptotically vanishing sound quality - laptops will become popular again in order to make voice telephone calls.
